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

Serial.print(angle); // print the angle

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
