Step 1: Things You Need for This

1602 IIC display:

1602 SPI display:Arduino Uno : I2C module for LCD

Step 2: Connect the IIC Module to the Display

Connect the IIC module to the back of the display as shown in the image.

Step 3: Install the Libraries in Your Arduino IDE

For the i2c lcd module download the given library and paste it in libraries folder of arduino as shown in image :https://drive.google.com/file/d/1CTRETQsYqGYu9u5PA...

Step 4: Getting I2C Address of IIC Display Module

So to get the i2c address of i2c display just connect the lcd to Arduino as given -Lcd. ArduinoSDA. >. A4(sda)SCL. >. A5(scl)Vcc. >. 5VGnd. >. GndThen upload the code i2c scanner to the arduinohttps://playground.arduino.cc/Main/I2cScanner/

then open the serial monitor and you'll find your i2c address on serial monitor as mine is 0x27

Step 5: Test the Hello World

go to examples then under arduino liquid crystal i2c library you'll find hello world code and just change the i2c address with the address you got by i2c scanner and upload the code and hello world will be printed on the screen. Hide
