How To Connect An I2c Lcd Display To An Arduino Uno Tutorial Youtube Arduino lcd i2c. in this arduino lcd i2c tutorial, we will learn how to connect an lcd i2c (liquid crystal display) to the arduino board. lcds are very popular and widely used in electronics projects for displaying information. there are many types of lcd. this tutorial takes lcd 16x2 (16 columns and 2 rows) as an example. Connect lcd i2c display to arduino uno r4 according to the provided diagram. connect the arduino uno r4 board to your computer using a usb cable. launch the arduino ide on your computer. select the appropriate arduino uno r4 board (e.g., arduino uno r4 wifi) and com port. go to the libraries icon on the left side of the arduino ide.
How To Connect An I2c Lcd Display To An Arduino Uno Tutorial The first step is to find a working library of them. i use liquid crystal i2c, and wire. link for liquid crystal here , link for wire here. the second step is to add the libraries to your arduino ide, to do that you go to sketch > include library > add zip library then find it in files. if it works, you should get a message saying it worked. You can copy the code by clicking on the button in the top right corner of the code field. * arduino example code to display custom characters on i2c character lcd. more info: makerguides * . liquidcrystal i2c lcd = liquidcrystal i2c(0x27, 16, 2); change to (0x27,20,4) for 20x4 lcd. Subscribe: aymaanrahman?sub confirmation=1in this video, i show you how to use a i2c lcd display with an arduino uno!♦ parts listardu. After wiring the lcd, you will need to adjust the contrast of the lcd. on the i2c module, there is a potentiometer that can be rotated with a small screwdriver. now, turn on the arduino. you will see the backlight light up. as you turn the potentiometer knob, the first row of rectangles will appear.

Now we will see the wiring diagram of i2c lcd with arduino uno. the wiring diagram is straightforward. in this circuit, we are using the default i2c communication pins of arduino uno. in this board, a5 is the default scl pin, and a4 is the default sda pin for i2c communication. Arduino i2c lcd tutorial. circuitgeeks november 24, 2023. in the previous arduino lcd tutorial, you have noticed that the classic parallel lcd consumes a lot of pins on the arduino. even in the 4 bit mode, it requires at least 6 digital i o pins on the arduino. so in many projects where you use the classic parallel lcd, you will run out of pins.
