Arduino 4 Channel Infra-Red Remote Controlled ON/OFF Switch
The project published here allows turning ON and OFF lights fans using infra red remote. Project consist 4 channel Nano relay shield, low cost infra-red remote. The project can control Fan, AC lamps AC230V/AC110V or DC load upto 7Amps.
Features
- Supply 12V DC
- Current consumption 250mAmps ( When All Relays are in On State)
- Relay Switch Load 7Amps AC /DC
Arduino Pins
- 4 Relay: Arduino Pin D2, D3, D4, D5
- Infra-Red Receiver TSOP1838: Arduino Pin D6
Decoding the IR code is important to pair any Infra-Red transmitter with the receiver, check bellow link to understand the decoding of IR signal from various infra-red remote protocols.

Infra-Red Code Decoder (Arduino Code)
#include <IRremote.h>
int IRPIN = 6;
IRrecv irrecv(IRPIN);
decode_results result;
void setup()
{
Serial.begin(9600);
Serial.println(“Enabling IRin”);
irrecv.enableIRIn();
Serial.println(“Enabled IRin”);
}
void loop()
{
if (irrecv.decode(&result))
{
Serial.println(result.value, HEX);
irrecv.resume();
}
delay(500);
}
