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.

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 have provided PCB layout, circuit diagram, and Gerber files so that you can build or directly order this Relay Driver Module. Previously we have built 4-channel Relay Driver Module, but this ...

An Arduino Uno relay module controls high-power devices by switching electrical circuits on or off. It's commonly used for home automation, industrial automation, and controlling lights, motors, or ...

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.

Arduino Uno is powered with a 12V DC adaptor/power source. The relay module and Bluetooth module can be, in turn, powered using a board power supply of Arduino Uno. Author’s prototype is shown in Fig.
