Part 8: Using Servo Motors with Arduino
In this lesson we learn how to contorl as servo motor using a push button switch. when a push button is pressed, the servo start moving to the right or left until reachers 180 and then returnes to 0 degree. Code is fully explained and demonstrated. this code is for single sensor.
