Deluxe Servo Tester
Many of us who read SERVO Magazine and Nuts & Volts ( www.nutsvolts.
com) have worked with hobby servos of one sort or another. Originally, they
were controlled with joysticks and trim tabs on radio control (RC)
transmitters, but now we frequently control them with microprocessors.
Knowing the correct timing signal to send to get the servo to a specific
position is frequently a trial-and-error exercise since not all servos are
identical. This article will help you build a device which tests and positions
servos, giving you the specific timing needed for your programs.
