Description

Step 1



We used a 1602 I2C LCD purchased from amazon. The LCD is clearly marked with GND, VCC SDA and SCL.

The LCD SDA > Pin 20 on the Arduino Mega
The LCD SCL > Pin 21 on the Arduino Mega
The LCD GND > GND on the Arduino Mega
The LCD VCC > +5V on the Arduino Mega

There is an adjustment for the backlight on a potentiometer on the back.

If you don't know the I2C address of the LCD display see the I2C Scanner Project here
