Course Description
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.
why you should take this course?
Uses an innovative circuit design to reduce power consumption
You do not need external components like resistors, capacitors, or crystals
The circuit is perfect for microcontrollers that are always running but don't maintain data or perform much computation during their operation
It reduces the power consumption to the point where they can be powered off without risk of data corruption
It's also great for powering tiny circuits (like RFID tags) without having to worry about battery life
No more worrying about rebooting your system or buying new batteries because of low power
-----------------
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.

If you want to do any of these things, just enroll in the course. You have a 30-day money back guarantee if you don't like it. And I'm always improving my courses so that they stay up to date and the best that they can be. Check them out, and enroll today!
More About Ashraf:
I've always tried to live life presently and to the fullest. Some of the things I love to do in my spare time include football, biking, traveling to new places, watching sports (huge football fan here!), and sharing meals with friends and family.
In 2012, I graduated with my Bachelor of Mechatronics Engineering at Azhar University - one of the top schools in the country. While there, I was fortunate to make Embedded Systems project using Arduino, PIC Microcontroller and other modules. After graduating, I worked at My own university as a Teacher Assistant . I followed that stint with a contract at a local College where I discovered how amazing it is to share your knowledge offline, which made me eager and eventually found myself starting my own online learning journey. I helped more than 100k student since then. Most recently. Throughout this time I built my Educational Engineering School Online brand to teach others the skills that I have. Now I only do things I love each day.
I want to show you how to be a better Embedded System creator, make money from your skills, and live the life you dreamed of.
