· The purpose of this project was to use PID control in a unity feedback structure to stabilize an unstable system.
· The system chosen was a ball balanced along a track. The system was capable of tracking a given reference point for the ball on the beam, and return the ball to this point after an external disturbance was applied.
· An Arduino microcontroller was used to interpret data from a linear potentiometer tracking the ball and actuate a servomotor that would stabilize the system.
