How to Setup I2C Communication on the Arduino

To demonstrate how to use I2C on the Arduino, let’s build a project that sends data back and forth between two Arduinos. This project will read the position of a potentiometer connected to a master Arduino, send the information over I2C, and change the blink rate of the LED on the slave Arduino.
