arduino lcd display circuit pricelist

When I started with Arduino I found it difficult to figure out which board I should buy, which components I should buy with it, and whether or not I really needed a starter kit. To help anyone figure out the costs involved for a new Arduino project (including boards, kits, shields, and components) I put this guide together.

Typical costs of an Arduino are between $22 and $46. The cheapest Arduino is the Nano Every which is available from $11.90 and includes a 20Mhz processor and 6KB of SRAM. Additional purchases for an Arduino project typically include cables, wires, and other components which can add between $10 and $20 to the cost. Projects with greater complexity or more components increase this cost.

Some of these boards are available in starter kits. Buying an Arduino starter kit typically adds $50 to $70 to the cost of getting started. Arduino boards that can be found as part of a starter kit include the UNO Rev 3, the MKR WiFi 1010 and the MKR1000.

Summing this all up, typical costs for starting with a simple Arduino project are between $30 and $70, depending on the board and components that are involved. More complicated projects, involving wireless connectivity, image and sound processing, or controlling motors are typically more expensive due to the requirements for faster Arduino boards and complicated components and circuitry.

Arduino starter kits include an Arduino and accompanying components and instructions for making a series of curated projects that offer an introduction on how to work with Arduino. These kits cost between $77 and $114. The components can be purchased separately for a similar price, and the instructions are typically published by Arduino online as well.

Arduino starter kits are worth it for those who do not want to spend time ordering individual components. While the kits typically cost more than purchasing the components from other websites, this cost is not significant compared to the amount of time it would take to acquire the components required for the beginner Arduino projects.

I found the Student Kit to be interesting as it’s the cheapest and includes a multimeter. The included instructions seem to hold your hand a lot as it’s designed for students who are still learning about electricity and circuits. If you have even a basic understanding of circuits, consider one of the others (the Starter Kitor the Explore IoT) instead.

Components are the elctronics that an Arduino project uses to function. These components typically form circuits that the Arduino has some control over, and can be used in conjunction with or as part of various shields. Examples of common components for Arduino projects include breadboard, wires, LEDs, and motors.

I find you spend more on an Arduino project in the discovery phase – when you’re experimenting with the way wires / configuration whatever else will work. If putting the Arduino to work, particularly if building multiple units (e.g. an array of Arduino powered sensors), money can be saved by not buying prototyping material, such as breadboards.

Looking for an idea of how much typical Arduino project components cost? Check out the guide I recently wrote here: chipwired.com/useful-arduino-components/

Shields are expansion boards that ‘plug’ into an Arduino to give it extra capability. This capability can be extra processing power, more connectivity (such as adding WiFi), adding sensors, or controlling other devices (such as motors). Compatible shields can be made by Arduino themselves or by third parties. It’s important to look at compatibility with your Arduino when adding a shield.

Arduino shields typically cost between $3 and $30. Cheaper shields usually expand the ability to interface with simple circuits, such as LEDs and switches. More expensive shields can be self-contained processing boards, such as a camera with image processing capability built into the shield. Shields can be purchased from the Arduino website or from third-parties.

A prototype shield usually offers extra space to connect wires and other circuit components. It can be made of breadboard or of PCB which requires soldering. Sometimes for convenience they’ll include buttons and LEDs that can be used in your circuits.

A multifunction shield is a bundle of components included on a shield that offer a convenient interface for the circuits you’re building. These components typically include buttons and switches, LEDs, display modules, potentiometers, and other similar components. Multifunction shields, similar to prototype shields, can be useful when experimenting with a design.

I took the price data from Adafruit, SparkFun, and the official Arduino website. Check the References section at the end of this guide for more detail.

My source for these prices was the official Arduino store and some third party suppliers (SparkFun – because it’s popular; Element14 – because they’re my local supplier and I like the coffee shop below their office). Other places I’ve usually found reliable for Arduino supplies are AdaFruit and Amazon. For more details on the references I’ve used, check out the References section at the end of this guide.

We have published quite a number of tutorials using different displays with the Arduino, with the most recent being the tutorial on displaying graphics on all kind of displays with Arduino. For today’s tutorial, we will look into achieving more with displays by implementing a menu based system with the Nokia 5110 LCD display and the Arduino. The menu is one of the easiest and most intuitive ways through which users interact with products that require navigation. From mobile phone to PCs, its applications are endless. Today we will explore how to add this cool feature to your Arduino project.

At the heart of today’s project is the Nokia 5110 LCD Display. The Nokia 5110 LCD is one of the most popular LCD display among makers. It was originally developed for use as a screen for cell phones and was used in lots of mobile phones during the 90’s. The display uses a low power CMOS LCD controller/driver, the PCD8544, which drives the 84×48px graphics display. In a normal state, the display consumes about 6 to 7mA which makes it quite ideal for low power devices. We have published quite a number of tutorials on this display that might help you understand how to drive such a display.

To showcase how to create the menu on a display with the Arduino, we will build a simple demo menu with three pages.  To navigate through the menu, we will use 3x push buttons. The first to scroll up, the second to scroll down and the third one to select a highlighted option. The first screen/page of the menu will serve as the home page and will host the options that open the next two screens/pages. The second page will open after the first menu option on the homepage has been selected. Users will be able to change the contrast of the display using the up and down push buttons to increase or reduce it respectively. By pressing the select button, users will be able to go back to the home page. The second option on the homepage displays the third page, where users will be able to turn the backlight of the display on/off by pressing the select item button.

To make the schematics easy to follow, a pin map of the connection between the Arduino Uno and the Nokia 5110, which isthe major component, is shown below.

Looking at the schematics, you will see that the push buttons are connected to the Arduino without the common pull-up or pull-down resistors. This is because we will use the Arduino’s internal pull-up resistor. You can read more about using pull-up/down resistors here. If you have any challenges understanding the concept, do reach out to me via the comment section.

To be fair, the code for today’s tutorial is a little bit complex and while I will do my best to break it down and ensure you understand the basics, it might take you building your own menu to fully grab the concept. The code for today is heavily dependent on two major libraries; The Adafruit GFX library and the Adafruit Nokia 5110 LCD Library. The Adafruit GFX library is probably one of the libraries we use the most in our tutorials. It makes it easy to display graphics and perform simple animations on supported displays. The Nokia 5110 LCD library, on the other hand, reduces the amount of work and code required to interact with the LCD.

We start the code as with other sketches by including all the libraries required for the project which in this case, are the Adafruit GFX and Nokia 5110 LCD libraries.

Next, we write the void setup function. Here we declare all the pins to which the push buttons are connected as inputs and set digital pin 7 as output since the Light pin of the LCD is connected to it. This pin will be used to turn the backlight on/off later on.

After setting the pin modes, we initialize serial communication, initialize the screen, and set the screen contrast to 50 which serves as a default value (to be varied later using the menu buttons) and use the display.display() function to apply the changes.

The state of the buttons is then fed into a series of if-else statements which checks which button was pressed and which of the screens is currently being displayed to determine what action is done next. For instance, the first if statement checks if the menu is currently on page 1 and if the up button is pressed. If this is the case, it then checks the position of the menu cursor and adjusts it accordingly.

Go through the schematics one more time to ensure everything is connected as it should be, then connect the Arduino to your computer and upload the code. After a couple of seconds, you should see the menu displayed on the LCD and it should respond to the push buttons when pressed.

The LCDduino board enables users to create many applications/projects that require a 16×2 LCD display and Arduino. The board has the exact size of 16×2 LCD and can be installed on the backside of the LCD. This is a low-cost solution that has onboard Arduino + LCD so no extra Arduino Nano or Arduino board is required. The Arduino compatible hardware includes onboard programming and boot-loader connectors, Atmega328 microcontroller, and 16×2 LCD interface. Each Arduino I/O Pin including the VCC and GND is exposed to the connectors for easy connection with sensors and other devices. The board enables the easy interface of many devices and sensors. The operating power supply is 7 to 15V DC.

After the board assembly, the brand new Atmega328 microcontroller requires burning the bootloader before it can be programmed using Arduino IDE. Refer to the connection diagram and follow the links below to learn more about bootloader and Arduino IDE programming.

Arduino example code is provided below to test the project. This code will help you to convert this board into a 0 to 5V Voltmeter. Just connect the DC source at analog in A0 to measure the DC voltage.

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.

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:

In this tutorial, we will display the custom characters on an LCD 16×2. Liquid crystal display (LCDs) offer a convenient and inexpensive way to provide a user interface for a project.

By far the most popular LCD used is the text panel based on the Hitachi HD44780 chip. This displays two or four lines of text, with 16 or 20 characters per line (32 and 40 character versions are also available, but usually at much higher prices).

We want to define and display custom characters or symbols (glyphs) that we have created. The symbols we want to display are not predefined in the LCD character memory.

A library for driving text LCD displays is provided with Arduino, and you can print text on your LCD easily as on the serial monitor because of LCD and serial share the same underlying print function.

To display custom characters on LCD, we must first know about the LCD dot matrix means pixels in LCD. There are 5 pixels in rows and 8 pixels in columns means every character is a combination of 5*8 dots.

Each big number is built from six of these glyphs, three forming the upper half of the big digit and three forming the lower half. BiDigitsTop and bigDigitsBot are arrays defining which custom glyph is used for the top and bottom rows on the LCD screen.

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.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

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:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

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.
