Raspberry Pi Camera Panning with a Servo Motor

In this tutorial, the RPi is used to demonstrate pulse-width modulation (PWM) and apply it to servo motor control. Then, the servo is used to control the panning of a camera - which is also controlled by the native camera port on the Raspberry Pi. This tutorial is a simple introduction that can be expanded into a full 360° controllable camera project, or a project involving a robotic arm, or any project involving servo motors or PWM-controlled devices.
