Tuning a servo to the correct pulse width

Servos can have their arms rotated to specific angles by sending them different electrical pulses. The angle that the arm moves to will be controlled by the width of the electrical pulse. Before setting these angles, each servo must first be configured with the correct minimum and maximum width settings.

This recipe will show you how to do that. This configuration will be required whenever you want to use servos in your projects.
