In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

This is the companion code for the oorail Tech Tuesday Episode #3 video. In this video we walk you through using a 16-channel 12V DC relay board to power Peco PL-11 point motors. You can find the ...

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 ...

This IR motion sensor relay switch circuit is designed for use with all kinds of medium-power automobile/domestic 12V DC loads. It is a simple solid-state relay (SSR) switch, controlled by a standard ...

Nowadays, people have smartphones with them all the time. So it makes sense to use these to control home appliances. Presented here is a home automation project using a simple Android app, which you ...

In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC ...

The Sourcecode is based on an elektor project (https://www.elektormagazine.de/magazine/elektor-201610/39858). Compatible with HC-05/06 slave mode, support Bluetooth ...
