Control Servo with single push button with Arduino

This is Arduino code to control a servo using push button and Arduino. For step by step details please watch video.

Servo control with push button Arduino sketch

  /*
 Controlling a servo with Push button with Arduino
 when a push button is pressed, the servo start moving to the right or left until
 reachers 180 and then returnes to 0 degree.

Control Servo with two push buttons with Arduino

In this video you will learn how to control a servo using two push buttons and Arduino. There are


   /*
 Controlling a servo with two Push buttons with Arduino
 when Left  push button is pressed, the servo start moving to the left until it reaches 180( or zero) degrees
 when Right  push button is pressed, the servo start moving to the right until it reaches 180( or zero) degrees
At any instance if the button is released, servo stops
