Auto Power Off Circuit for Microcontrollers: Save Power

In this course, You will learn how to build an Auto Power Off Circuit for Microcontrollers: Save Power.

You can use this circuit to auto-power off the Arduino, ESP32, ESP8266, PIC Microcontroller or any other microcontroller.

This circuit allows you to cut off power completely when the microcontroller is not executing any task. In other words, as soon as the microcontroller finishes executing a task it turns itself off via software. This is a great way to make batteries last longer in your electronics projects.

The main feature of the auto power-off circuit is that it cuts off the power completely. So, no power consumption at all when the microcontroller is not executing a task.

The Latching Power Switch Circuit, also known as an Auto Power Off Circuit allows you to turn off your microcontroller via software, whether you’re using an ESP32, ESP8266, Arduino, or any other board. This circuit is especially useful to save power: the microcontroller turns itself down after executing a task.

In our example, we’ve used a pushbutton to close the circuit to provide power to the microcontroller, but you can use any other component to close the circuit – like a reed switch for example. We hope you’ve found this tutorial useful and you’re able to use it in your electronics projects to save power.
