A servo system demonstration using an AAT angle sensor, an Arduino, a stepper motor, and a modified clock.
The core of the demonstration uses an NVE AAT003 angle sensor, an Arduino Uno, a SparkFun ROB-12779 stepper driver. In addition, an AD004 magnetic proximity sensor is used to initialize the clock hand to the 12:00 position.
