Use Same Push Button for Turning ON/OFF and other Functions

In this video, I’ll show you how to design and build a professional auto power off circuit that turns your device on and off with just a single push button. We’ll go step by step, from basic concepts to the final working circuit, using a P-Channel MOSFET, an optocoupler, and an STM32 microcontroller.

By the end, you’ll learn how to:

Save battery life with auto shutdown

Replace mechanical switches with an electronic power switch

Use the same button for on/off AND device settings

Make your projects look way more professional
