Pushbutton Power Switch for Arduino

Wayne Holder designed a simple pushbutton power on/off circuit that works with most Arduino boards:IMG_7746

Pushbutton Power Switch

This article shows how you can use a simple, ultra low current pushbutton, an LED and a few I/O lines to implement pushbutton power switch for an Arduino.


Simply press the pushbutton for a few seconds and the Arduino will power on and run code.  Then, push and hold the pushbutton until the LED illuminates and then release the button to switch power off.
