IR Remote Receiver

Z2M Part: EMC-00008-A/B / EDS-00005-A

Receive and decode IR remote signals.

Circuit Diagram

Wire Connections & Pin Configuration

Wire Color Connections:

Yellow → Digital Pin 7 to IR receiver OUT
Red → 5V to IR receiver VCC
Black → GND to IR receiver GND

Pin Configuration:

Arduino Digital Pin 7 → IR receiver OUT
Arduino 5V → IR receiver VCC
Arduino GND → IR receiver GND

Arduino Code

Edit

#include <IRremote.h>

const int RECV_PIN = 7;   // IR Receiver connected to digital pin 7
IRrecv irrecv(RECV_PIN);  // Create IR receiver object
decode_results results;   // Variable to store decoded results

void setup() {
  Serial.begin(9600);     // Initialize Serial Monitor
  irrecv.enableIRIn();    // Start IR receiver
  irrecv.blink13(true);   // Blink onboard LED when signal is received
}

void loop() {
  // Check if IR signal is received
  if (irrecv.decode(&results)) {
    // Print the received IR code in HEX format
    Serial.println(results.value, HEX);
    irrecv.resume();  // Prepare to receive the next signal
  }
}

Instruction Details

Wiring: Connect IR receiver VCC to 5V, GND to GND, OUT to Digital Pin 7.
Library: Sketch → Include Library → Manage Libraries → search "IRremote" → Install.
Upload Code: Tools → Board → Arduino Uno. Tools → Port → select your COM port. Click Upload button.
View Output: Open Serial Monitor (Tools → Serial Monitor) at 9600 baud. Point IR remote at receiver and press buttons. Hex codes display. Onboard LED blinks when signal received.
