In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

That’s it for this tutorial guys, thanks for reading. If you made some cool projects based on this or you just want to ask questions about this tutorial, feel free to reach out via the comment section below.

Hi guys, over the past few tutorials, we have been discussing TFT displays, how to connect and use them in Arduino projects, especially the 1.8″ Colored TFT display. In a similar way, we will look at how to use the 1.44″ TFT Display (ILI9163C) with the Arduino.

The ILI9163C based 1.44″ colored TFT Display, is a SPI protocol based display with a resolution of 128 x 128 pixels. It’s capable of displaying up to 262,000 different colors. The module can be said to be a sibling to the 1.8″ TFT display, except for the fact that it is much faster and has a better, overall cost to performance ratio when compared with the 1.8″ TFT display. Some of the features of the display are listed below;

TheTFT Display, as earlier stated, communicates with the microcontroller over SPI, thus to use it, we need to connect it to the SPI pins of the Arduino as shown in the schematics below.

Please note that the version of the display used for this tutorial is not available on fritzing which is the software used for the schematics, so follow the pin connection list below to further understand how each pin of the TFT display should be connected to the Arduino.

When connecting the display, ensure that has a voltage regulator (shown in the image below) before connecting it directly to the 5v logic level of the Arduino. This is because the display could be destroyed if the version of the display you have does not have the regulator.

In order to allow the Arduino to work with the display, we need two Arduino libraries; the sumotoy TFT ILI9163C Arduino library which can be downloaded from this link and the popular Adafruit GFX Arduino library which we have used extensively in several tutorials. Download these libraries and install them in the Arduino IDE.

For today’s tutorial, we will be using the bigtest example which is one of the example codes that comes with the sumotoy ILI9163C Arduino library to show how to use the TFT display.

The example can be opened by going to File–>Examples–>TFT_ILI9163c–>bigtest as shown in the image below. It should be noted that this will only be available after the sumotoy library has been installed.

Next, an object of the ILI9163c library named “display” was created with CS and DC parameter as inputs but due to the kind of display being used, we need to include the pin of the Arduino to which the A0 pin of the TFT display is connected which is D8.

With the libraries installed, open an instance of the Arduino IDE, open the examples as described initially, don’t forget to make the A0 pin (D8) correction to the code then upload to the Arduino board. You should see different kind of text and graphics being displayed on the screen. I captured the screen in action and its shown in the image below.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

For 5 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-RA8875.

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

Let"s get started with this creative Arduino project, where you"ll learn about the TFT LCD touch screen and how to use it to create your own colourful calculator. For a basic understanding of touch screen & LCD, a cheap TFT 2.4" Arduino shield is used to create this project. For creating a similar project, one should follow the steps and edit the code for better understanding.

The shield connects ILI9341"s data pins 0-7 to Arduino"s digital pins 2-8 (allowing parallel communication, not SPI. ILI9341"s RESET goes to Arduino analog pin A4. CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.

Now, open Arduino IDE and select Sketch -> Include Library -> Add .ZIP library. A browser window will open navigate to the ZIP file and click “OK”. You should notice “Library added to your Libraries” on the bottom-left corner of Arduino, if successful.

You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with BMP image files, and these images can be displayed on our TFT LCD screen using the Arduino Program.

The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the programming terminal of your Arduino UNO with some insulator, just in case if the terminal comes in contact with your TFT LCD screen.

While in theory an Arduino can run any LCD, we believe that some LCDs are particularly suited to being an Arduino LCD display. We"ve currated this list of LCD displays that will make any Arduino-based project shine.

First is the interface. All of these displays support SPI. Builders often ask themselves (or us) "which interface uses the fewest GPIO pins? AND is that interface fast enough to update the screen at an acceptable rate for my application?" When using the relatively small procesor of the Arduino, SPI is usually the best interface because it takes few wires (either 3 or 4) however it does limit the overall size (number of pixels) that can be quickly controlled. I2C is another choice of interface to leave GPIOs open. We tend to recommend SPI over I2C for Arduino displays because SPI is quicker and better at handling more complex data transfer, like pulling image data from an SD card.

Which brings us to the second factor in choosing an Arduino display: the number of pixels. We typically recommend a display with a resolution of 320x240 or less for use with Arduino. Take for example a 320x240 24-bit display. Such a display takes 230,400 bytes *(8 + 2) = 2,304,000 bits for a single frame. Divide that by 8,000,000 (Arduino SPI speed of 8MHZ) = 0.288 seconds per frame or 3.5 frames per second. 3.5 fps is fast enough for many applications, but is not particularly quick. Using fewer bits-per-pixel or a display with fewer pixels will result in higher frame rates. Use the calculator below to calculate the frame rate for a display using SPI with an Arduino.

Third, we want to recommend displays that are easy to connect to an Arduino. Each of these displays has a ZIF tail or easily solderable throughholes, so no fine pitch soldering is needed. These displays can either be brought up on the CFA10102 generic breakout board, or with a custom CFA breakout board.

Most character displays can be run via Parallel connection to an Arduino. You"ll want to make sure you can supply enough current to operate the backlight.

The main component of Me TFT LCD Screen module is a LCD display communicating with Makeblock Orion through serial port to show characters and graphics of different size and colors. The module is integrated with MCU and memory chip, and the Chinese characters, letters, and figures stored in the memory chip can be invoked easily through the serial port. Its blue/gray ID means that it has a double-digital signal port and needs to be connected to the port with blue or gray ID on Makeblock Orion.

Since the port of Me TFT LCD Screen has blue/gray ID, you need to connect the port with blue or gray ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example, you can connect to ports No. 5 as follows:

When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its TX and RX pins should be connected to TX and RX ports respectively as follows:

If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me TFT LCD Screen. This program serves to display different graphics and characters through Arduino programming.

This module (Me TFT LCD Screen – 2.2 Inch) contains a voltage converter, an STM32 chip, and a serial flash memory of 2M. In contrast with other displays, it needs only serial port for communication, so it is easy to operate and connect.

This example demonstrates how to draw text on the Arduino GLCD screen when connected to an Arduino. The Arduino reads the value of an analog sensor attached to pin A0, and writes the value to the LCD screen, updating every quarter second.

Define the pins you"re going to use for controlling the screen, and create an instance of the TFT library named TFTscreen. You"ll reference that object whenever you"re working with the screen.

We are undoubtedly in a technological era. We have evolved from sending letters to sending emails and texts, walking to driving, and ultimately even flying. Technology has changed the world immensely. At the core of this evolution lies tech gadgets and devices that most do not pay proper attention to. There are sensors (light, motion, and sound sensors), LEDs, switches, motherboards, et cetera. However, this article shall discuss a unique gadget known as an Arduino board. Arduino has been used in so many academic and scientific-based projects over the years. Some have even used it to develop incredible inventions that we have implemented to date. Arduino boards are super powerful and efficient and, when well implemented, offer excellent output. So how can you implement an Arduino board to make fascinating projects? We will get to that later on.

Have you ever made an Arduino project? Are you thinking about developing an Arduino project? Are you looking for a challenging Arduino project to take on? Or are you just looking to up your game in Arduino projects? Well, this article might help you out. In this awesome Arduino projects article, we shall go through 15 awesome projects that range from simple to borderline fascinating. We shall cover:

These projects are all pretty interesting to take on. What’s more, the level of complexity differs. If you are advanced in Arduino projects, there is a category for you. If you are a beginner, then there is one for you too. For those looking to develop crazy cool projects, then there is a section for you too. So follow along and let us help you find that perfect Arduino project for you.

The best part is that you get to instruct your board on what to do via instructions you set and upload onto the board’s microcontroller. To achieve this, you must implement theArduino programming language, which is based on wiring, and the Arduino software, which is based on processing.

There are a couple of reasons why many people have used Arduino over time to develop their projects. What’s more, the Arduino community has had consistent growth too, so why is this? Well, here are a couple of reasons why:

Inexpensiveness – Arduino boards are pretty cheap compared to the many microcontrollers that exist. You can get an Arduino board for less than $50 to kick-start your project.

Cross-platform – Arduino software runs on Linux OS, Macintosh’s OSX, and the Windows OS. However, many microcontrollers that exist are typically limited to the Windows OS.

A clear and easy-to-understand programming environment – If you are looking for an easy-to-use microcontroller for your project, then Arduino has got you. Arduino has a pretty simple interface that you can use with ease. What’s more, its software is also super easy to use and flexible enough to be used by advanced users.

Extensible and open source software – You know how people love custom things, from t-shirts to smartphone casing and so on. Well, it provides you with this option. Since the Arduino software is open-source, that means that you can add on the functionalities that you want to be implemented, plus you can also add on extensions, pretty cool. Of course, you have to be good in C++ libraries to achieve this, but it does make Arduino a rather unique microcontroller to use.

An extensible and open-source hardware – Arduino board plans are published under a license category known as creative commons; this means that experienced circuit designers can develop their versions of the Arduino module. They can also extend the current module to improve its functionality; this means that the efficiency of this microcontroller can only go up over time.

Using Arduino, you can make a lot of fascinating projects, such as a clap-activated light (a bulb that lights when it detects a clap) or a smoke detector. You can also merge up an Arduino microcontroller with other gadgets such as a motion detector to achieve more complex projects.

Developing an Arduino project can be a tedious process, especially when you do so in a disordered manner. So in this section, we shall go through the steps that you need to take to develop an Arduino project with ease:

To get an Arduino project up and running, you have to provide a set of instructions that have to be followed by the microcontroller. TheseThese instructions are provided in the form of a program that you write on the Arduino IDE. The IDE refers to the programmer. When you are done writing the code for your program, you then upload it via the IDE.

Sometimes, you will encounter errors in your project. That’s pretty common. Errors in a project can be caused by a lot of things, maybe you did not write the project’s program well, or perhaps you did not assemble the Arduino board appropriately, et cetera. If you encounter an error in your project, you have to troubleshoot. You cannot fix a mistake that you don’t know. Hence you have to locate the error first, then fix it accordingly. If the error is in the program, you might have to make some code adjustments to make it work. For hardware errors, this might result in some desoldering.

Now that we know all about Arduino and Arduino projects, it is about time we dive into what we have all been waiting for, the 15 crazy Arduino projects!

In this section, we shall go through 15 of the craziest Arduino projects in the world. We shall start with beginner-level projects and up the intensity as we move on higher up the scale of crazy Arduino projects. All the projects we shall go through can be done at home; hence you do not have to worry about getting a lab!

If you are a beginner in Arduino, this section might help you out a lot. In this section, we shall discuss some pretty easy to make projects using Arduino; hence stick around:

The traditional solar systems have one glitch. They only face one direction. That means that at some point, this solar system doesn’t take in as much energy from the sun as it should due to the sun’s angle. However, you can counter this with ease while using Arduino; here is how.

Using a light sensor having four LDRs, two motors, and an Arduino board, you can develop a modern solar tracking system that follows the sun’s movement. The system ensures that the solar panels get hit by maximum sunlight every time hence absorbing maximum energy.

A simple, beginner-level tilt sensor is simply a switch that turns on or off depending on the angle of the set sensor. When using Arduino, you can develop such a sensor that is crucial for detecting single-axis tilt. It is a fun project to take on and a great one to boost your knowledge of Arduino.

However, what this modern-day home security systems have in common is that they are also pretty expensive, so how can you capitalize on that? Well, here is the answer to that question. Using Arduino and GSM, you can develop a cheap home security system alarm that literally calls you on your cellphone in case of any intruder alert. It is both cost-effective and pretty efficient.

If you love physics, then here is a project for you. See, a rotary encoder can be defined as an electromechanical device that transforms the angular movement of a shaft to digital or analog code. Rotary encoders are mostly found in radio equipment such as handheld and amateur radio, whereby non-stop 360 rotation is necessary to tune a radio to the right frequency. Using Arduino, you can develop this crucial equipment as a project or as part of a more significant project.

In this project, we shall design an alarm clock that implements a real-time clock and Arduino for added functionality. A real-time clock (RTC) is a clock powered by a battery, and it’s used to measure time even when external power is absent. What’s more, this clock can also measure time even when its microcontroller has been reprogrammed.

The Arduino Mega Chessboard is a digitized Arduino chessboard that you can make at home using a touch screen, Arduino, and other basic components. To make the project even cooler, you can use a 3D printer to generate a case for the chessboard that matches your project’s purpose.

Are you sometimes annoyed by some personalities or celebrities on TV, and you feel like you have had “enough already?” Well, this happens to many people, so how about we solve this using an Arduino project to take things up a notch.

Using Arduino, you can develop a device that you can use to mute your TV whenever a personality or a celebrity that annoys you is about to speak. We call this project the “Enough already project” you get why. The enough already device uses a video experiment shield to decode closed captioning transcription tracks transmitted through the NTSC picture signal; this helps the device capture keywords such as “SNOOKI” and then mute the TV automatically. Earlier on, this type of tech was tested but never implemented. However, we are in an era whereby you can develop such a device at home.

If you like robotics, then here is an interesting Arduino project for you. The robot arm that uses a controller to allow manual control over it lets you explore the world of robotics immensely.

To make the robot arm, all you need are some essential components, an Arduino board, and a 3D printer to develop the hand’s frame. The robot arm has a couple of applications which include:

You know how complex weather stations monitor the climatic changes and the weather in general. What if I told you that you can make a weather shield that does the same job using Arduino! Well, not technically the whole shebang but using this weather shield project, you can easily tell the pressure and temperature without having to refer to phone apps or a weather station.

We have evolved from wooden coffee tables to glass coffee tables to the modern-day smart coffee tables with more functionalities than traditional tables. For example, a smart coffee table has lights that change according to the weight of the item or drink placed on it. Using Arduino and nano, you can generate a similar project.

Do you love plants but hate the struggle of constantly having to water them every now and then? Well, how about a nano Arduino project to solve this. The automated nano plant watering system project is a project that automates plant watering. Using Arduino, nano, and some basic codes and components, you get a pretty fascinating project, so your plants don’t die again.

An Arduino board has only one UART port. However, it is widely used by Arduino projects enthusiasts worldwide, hence earning a category in this article; let us see what it entails.

Using a specialized PCB that tracks your hand gestures and an Uno Arduino board, you can develop a device that can control your computer, music system, TV, and more using gestures. For example, with a flick of a wrist, you can change a channel, or with one snap, you can change the music playing in your music system. You can play around with this project to develop pretty cool functionalities.

You know how locking yourself out sometimes becomes a pretty bad habit? Well, how about a door that opened using your fingerprint? Now that would save you a lot of money. Using Arduino Uno, a fingerprint sensor, and some essential components, you can develop a fingerprint door lock.

LED is used in so many Arduino projects. They offer a sleek modern finish while also performing certain functionalities such as displaying time. Let us look at some pretty fascinating LED projects that might interest you.

Autonomous lighting systems seemed like an impossible feat back in the 80s. However, modern tech has proven this wrong. Using Arduino and LEDs, you can develop an autonomous lighting system. One that turns lights on when it gets dark and vice versa autonomously. Now that is a fascinating project.

You have probably heard of theTIC TAC TOE game if you love playing games. It is a fascinating game, and now, thanks to Arduino and LEDs, one that you can develop on your own to play with your friends and family. To play the game, you punch set boxes to reveal a 0 or an X.

Developing an Arduino project is pretty fun but also challenging, especially when you are working on a project that is not thrilling to you. We hope that this article has helped you find an exciting, cool, and fascinating project to work on. Remember that practice makes perfect!
