What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...

Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like lights, fans) in home automation or IoT projects. It is also very common ...

Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. So in this DIY project, we make a 4-Channel Relay Driver Circuit to ...

Arduino timer that lights a 50k volts taser, activated by a remote, a radio module, buttons or a radio-activated relay. The codes i provided are different ways to activate the taser, once the ...

This Python GUI program Controls the Relays using GPIO pins present in Raspberry Pi 4. Which is used for Simulating the Controls of Full Featured Microwave Oven with customizability and accuracy.
