Servo motor is two types - one is rotating about 0-180 degree & another one is rotating 0-360 degree.For a perfect stop you need a Arduino .
Here I am showing how to run your servo motor without
Arduino .
At first you have open the servo motor.Then you will see
the motor is connected with ic & three wires is connected
to the ic.
You have to cut all the wires & connected two wires ddirected with the motor.
In this way you can run your servo motor without Arduino
