TAP-28 Servo Connection

Servos contain internal electronics to convert a pulse train into a position. The PIC need only supply the pulse train to make the servo rotate; no switching of high currents is necessary.

Servos typically have a pigtail with a 3 pin female connector. The color code is usually one of two patterns:

Signal	Power	Ground
white	red	black
yellow	orange	brown

Any of the 3 pin connectors may be used to control a servo.
