Project III - 12. Controlling 4 Channel Relay using IR Remote (Arduino Based)

Controlling 4 Channel Relay using IR Remote

There are 12 butotns in IR Remote, so in this project we just use eight of them to controlling the relays. Button 1 to 4 is to turn on Relay 1 to 4, while button 5 to 8 is use to turn off Relay 1 to 4. LCD is used to display the pressed button data. Relay as an actuator that will directly control the electric, with Alternate Current especially.

Hardware Requirement

Relay Module 5V with 4 Channel
Arduino UNO
Xinda IR Remote Control Kit
LCD 2x16
Power supply +5 Volt
Jumper Cable

}

How it Works

1. Connect the Arduino with Peripherals needed
2. Plug in the Power Source on the device
3. Compile and upload the script program above to your arduino

4. Initial Display on LCD
