In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

It detects potential welded conditions and provides status updates through the serial monitor. Ideal for learning about relay management and timing functions, this project is built using Tinkercad for ...

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with having some delay. So today we are here with the same project but here we ...

To drive a relay from the Pi, one needs to cobble up a fairly simple circuit where the 3.3V GPIO pin turns on a transistor that drives the relay. This is such a common requirement that I figured ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...
