O. What is RelayModule Library? If I use it, how easier life will be ? If you have made some Arduino project with Relay Modules, you probably wrote some scattered code for relays. Scattered Code ...

The concept of automation is getting popularity among people these days and many of them control their lighting, climate, etc remotely at their homes. Several microcontrollers or microprocessors can ...

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, allowing the Arduino to control ...

This project is meant to control electrical appliances like fans and lights. You can configure two Yoda modules, one as receiver and the other as transmitter, to control relays that switch on fans and ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...
