Set Up

All of the components, except the Pittman motors, were powered with 5V DC. The Pittman motors were powered with 12V DC.

PICs

The PICs used were one "Master" 18F4520 and two "Slaves" 18F4431. The three PICs communicated via I2C, which enabled us to control the two motors by telling the master PIC what to do through Matlab.

H-Bridge
