I2C communication between PICs

Original Assignment

Microcontrollers commonly talk to each other using protocols such as RS-232, SPI (for "serial peripheral interface"), I2C (or I^2C, "I squared C," for inter-integrated circuit), CAN bus, or other. This project is to demonstrate bidirectional I2C communication between two PICs. A demonstration might have the value of an analog input (potentiometer) at one PIC displayed as a "light bar" on the LEDs of the other PIC board, and simultaneously vice-versa.
