Control Servo motor with a Push Button: Move Servo on ONE direction SPB-2

Control Servo motor with a Push Button: Move Servo on ONE direction SPB-2

This video shows how to control a servo motor using push button and Arduino such that when push button is pressed and keept pressed, the servo moves either from 0° to 180° or from 180° to 0° or set your own values.

We have 5 type of controling servo with push button

 Controlling a servo with Push button with Arduino
 this is code #2 to control servo with push button by Robojax (Robojax.com )

code #1 when push button the servo goes from 0° to 180° (or set your angle) and returns back
    Watch video for code #1: https://youtu.be/fPrPRZlGdvA
code #2 when push button the servo goes from either from 0° to 180° or from 180° to 0° (or set your angle)
    Watch video for code #2: https://youtu.be/T2HMJiy9b_I
code #3 when push button pressed AND keep pressed the servo goes from 0° to 180° (or set your angle)
    Watch video for code #3:https://youtu.be/58Qqh60FrMU 
code #4 two Push button used one is used to move servo to LEFT direction and the other for RIGHT direciton
