The servo is controlled by pulsing of its signal line. If you are using a Basic Stamp® microcontroller this is
done with the ‘pulsout’ command. Below is PBASIC code that will help you with basic control of a servo.
The code below will show center and then rotate the servo to the left and to the right then stop.
