DO NOT connect in any ways the main power supply that drive the LOAD to the arduino and transistor circuitry! Turn OFF the relay with delay You can use this code example to introduce a delay in your ...

A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller. By using an Arduino Uno and a single-channel ...

Electromechanical relays will require a transistor driver circuit in order to be driven by the Arduino. The typical circuit for driving a relay is the same as the transitor driver above with the ...

Relay-Interfacing-with-Arduino This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, ...

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

Hello, I'm going to share again with another project that helps many of you to solve the issue of how to switch the relay remotely. I have done a bit of a specific project for 2 chats that are ...

This project demonstrates how to create an anti-sleep alarm system for drivers using an Arduino Nano and a Relay Module. The system detects signs of drowsiness or fatigue in the driver and triggers an ...
