Description and Usage:

Utilize Arduino-based PID control of motor via comparison of actual (from encoders) and desired (from USB) wheel velocities.

Connections:

Header	Function	Signal Type
R-OSMC	Control motor speed and direction	pwm/logic output
L-OSMC	Control motor speed and direction	pwm/logic output
L-Encoder	Read data from encoder	logical input
R-Encoder	Read data from encoder	logical input
Arduino		See next table
