arduino 2.8 tft lcd tutorial pricelist
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.
For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.
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.
Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.
Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.
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:
In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.
The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.
This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.
The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.
The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:
In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.
Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6206 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.
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!
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.
We’ve done quite a number of tutorials on the use of several displays with Arduino boards and today we will add another tutorial to that list. We will look at the ILI9325 based 2.8″ touchscreen display shown below and how it can be used with the Arduino to deliver a better user experience for your projects.
For today’s tutorial, we will use the ILI9325 driver based, 2.8″ display from Geekcreit. The display comes as a shield so it’s ready to be used for Arduino based projects. It is an 18-bit color display with a total of 262,000 different color shades. The display has a resolution of 240 x 320 pixels with individual pixel control.
Today’s project involves some very simple tasks which we will use to demonstrate the capabilities of the display. We will create a button which when touched, will trigger the Arduino to display a message on the screen. At the end of today’s tutorial, we would have gone through how to create a user interface on the touchscreen, how to detect when the screen is touched and how to display data on the screen.
The Arduino Mega or any of the other Arduino board can be used for this project and the power bank comes in handy when the project is to be used in a standalone mode. As usual, the exact components used for this tutorial can be purchased via the links attached to each of them.
The 2.8″ TFT display used for this project comes as a shield with the form factor of the Arduino Uno. This makes it easy to connect the shield to boards like the Uno, Mega and Due, as all we need to do, is plug it directly into the board, eliminating all the mess made by wires. Plug the display to the Arduino as shown in the image below.
The fact that the display comes as a shield becomes a disadvantage when its used with the Arduino Uno as it occupies almost all the pins leaving just 2 digital pins and one analog pin for other uses. This can however, be overcome by using either the Arduino Mega or Due as they both work perfectly well with the display.
The code for this tutorial is heavily reliant on a modified version of Adafruit’s TFT LCD,GFX and touchscreen libraries. These libraries can be downloaded from the links attached to them.
As mentioned earlier, our focus for this tutorial will be to demonstrate, how UI can be created on the display and interpret touches to trigger actions. To achieve this, we will develop a simple sketch which displays a Youtube subscribe button. When the subscribe button is pressed, a text is displayed on the screen.
Next, we declare the colors to be used with their hexadecimal values and we create an object of the Adafruit TFTLCD library, indicating the variables used to represent the pins of the Arduino to which the display is connected.
We start by initializing the serial monitor and the display. After this, we set the orientation of the LCD and fill the screen with a black color to serve as the background.
Copy the code above and create a new Arduino sketct. Ensure the libraries are installed and upload the code to the setup described under the schematics section. Once the upload is complete, you should see the display come up as shown below.
That’s it for this tutorial guys. Feel free to expand this code for use in your projects and do not hesitate to let me know via the comment section if you have any questions.
