![]() ![]() 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. 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. ![]()
