This article will explore the workings of a relay module and provide a detailed guide on how to interface a single channel relay module with an Arduino.

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.

Power on the receiver circuit next and wait for five seconds as defined in receiver code. Press pushbutton (S1 or S2) in transmitter circuit to control the corresponding relay in receiver circuit.

Here we are making a simple project with Arduino which uses three basic components that are IR Sensor, Relay Module and DC Motor. Here we will interface IR sensor with Arduino to control DC Motor.

The Arduino Mega interfaces with a relay module to control high-power devices or circuits with low-power signals. This enables applications such as home automation, motor control, and switching ...

Patrick Thomas Mitchell has been once again been creating awesome Arduino speech recognition and relay board modules which have launched over on the Kickstarter website ...
