This simple circuit generates an adjustable servo signal to let you test and control servos. Based on the popular 555 timer, this kit is both educational and practical. Plug in your servo and battery and turn the blue potentiometer to see your servo move. You can also wire in your own potentiometer if you want to panel-mount this circuit.
