Lab 4 - Servo Motors

1. Servo Motor Controlled by Pulse Width Modulation from an Arduino

1. We add a delay after rotating the servo so it actually has time to rotate before running through the loop again.
2. Pulse widths range from 544 to 2400 μs, for angles from 0 to 180 degrees, so 45 degrees = (45/180)(2400-544) + 544 = 1008 μs.
3. The piezo speaker and the servo motor both use PWM from the arduino, which is not capable of reliably sending out both signals without any interference.
