This adjustment is made with a small screwdriver. Located on the back of the LCD screen is the I2C interface board, and on the interface is an adjustable potentiometer. You must now adjust that contrast setting. The LCD has an adjustment on it which needs to be approximately set to allow you to see characters on the display. Once you have the four connections to your LCD made, you can power your Arduino, which will provide power to the LCD. The chart below shows the connections needed. The connections include two for power and two for data.

How To Connect the I2C LCD to Arduino UNOĬonnecting the Arduino UNO to the I2C interface of the LCD requires only four connections. These pixels can display standard text, numbers, or special characters and can also be programmed to display custom characters easily. The LCD displays each character through a matrix grid of 5×8 pixels. If you happen to have an LCD without an I2C interface incorporated into the design, these can be easily acquired separately. An I2C LCD advantage is that wiring is straightforward, requiring only two data pins to control the LCD.Ī standard LCD requires over ten connections, which can be a problem if your Arduino does not have many GPIO pins available. The module features a controller chip handling I2C communications and an adjustable potentiometer for changing the intensity of the LED backlight. LCDs incorporate a small add-on circuit (backpack) mounted on the back of the LCD module. The character LCD is ideal for displaying text and numbers and special characters. We offer both a 2 x 16 LCD along with the larger 4 x 20 LCD.

Using an I2C interface, only two connections for an LCD character display are possible with stunning professional results. Adding an external display would typically require several of the limited I/O pins. The ability to interface to external devices readily is very enticing, although the Arduino has a limited number of input/output options.

The Arduino family of devices is features rich and offers many capabilities.

If you have the same problem as mine GET A SCREW driver then adjust the calibration of the i2c breakerĪnd then tadahh the text that ive sketch is now reflecting on the lcd, you can change the character in my code with yours. In case i do it reapedly beacause no text appears on the lcd, i ve already check the wirings and theres no problem with it. once done we have to verify the sketch by compiling once done then upload it to the board. Then Delete the 3rd line of my code with your address if you have the same address as mine you dont have to do it. or you can copy this code for i2c scanner sketch: // i2c_scanner #include void setup() after that the i2c scanner code will appear on the sketch. Once the library is already in the program now open the i2c scanner that we have recently downloaded, if your system cannot open the file > just left click on the file> open with> then locate the arduino uno ide.

#Download arduino wire library zip file#

Locate the arduinoliquid zip file that you have downloaded. download the i2c library using my repository link here: just click the >clone/ download then download ZIpSKETCH>INCLUDE LIBRARY>ADD. Lets go now for the software, first we have to download the arduino ide you can search that out and download the software: its very basic if you are going to start programming on arduino you shoud have the ide.Ģ.

The LCD GND to the GND on uno, the VCC to 5V, the SDA to the analog4, the SCL to the A5, look at the diagram, if you are using the non i2c breaker lcd then you have to use breadboard in this case the pins maybe diffrent.Ĭonnect it to your pc if the lcd lights up your wiring is correct. I am going to set up the hardware first, so we are going to connect the lcd to the board using jumpers In this instructable i am going to share how to connect i2c LCD to arduino board i will include the code/sketch that i use for the uno.
