Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol

Components used:

Circuit:

Code:

For Master, Project1_Master.ino

For Slave, Project2_Slave.ino

Output:

The I2C takes place between Arduino 1 to Arduino 2.

Arduino 1 which acts as a Master and Arduino 2 which acts as a Slave.

The potvalue of Arduino 1 displays potvalue of Arduino 2 and Arduino 2 displays potvalue of Arduino 1.
