Servo Speed Tester

This is probably the simplest Circuit to test a Servo, This circuit tests the speed of servo. Here we use potentiometer to controll the speed of the servo. By applying very less voltage like 4.5V and reducing the pot value, you can also adjust the position of the servo!

Check this Circuit which uses push switches to run a servo in Clock-wise and anti Clock-wise directions using 555 timer http://rookieelectronics.com/servo-tester/
