How To Control LED With IR Remote And Arduino UNO|Topped With Fun|Basic Arduino UNO Project With LED

 

 Circuit Diagram:

IR Decoder:-

#include <IRremote.h>

int IRpin = 2;

IRrecv irrecv(IRpin);

decode_results results;

void setup()

{

Serial.begin(9600);

irrecv.enableIRIn(); // Start the receiver

}

void loop()

{

if (irrecv.decode(&results))

{

Serial.println(results.value, DEC); // Print the Serial ‘results.value’

irrecv.resume(); // Receive the next value

}

}

IR Conroller:-

#include <IRremote.h>              //Includes IR Library

int RECV_PIN = 2;                   //IR Receiver Pin

IRrecv irrecv(RECV_PIN);

decode_results results;

#define BUTTON_1 0x1            //Paste Code Of 1st Button

#define BUTTON_2 0x2           //Paste Code Of 2nd Button

#define BUTTON_3 0x3          //Paste Code Of 3rd Button

#define BUTTON_0 0x33       //Paste Code Of 4th Button

#define BUTTON_OK 0x35   //Paste Code Of 5th Button

int blue_LED = 7;

int red_LED = 6;

int green_LED = 5;

void setup()

{

  pinMode(blue_LED, OUTPUT);

  pinMode(red_LED, OUTPUT);

  pinMode(green_LED, OUTPUT);

  

  irrecv.enableIRIn();

}

void loop() {

  if (irrecv.decode(&results))

  {

    if (results.value == BUTTON_0)

    {

      digitalWrite(blue_LED, LOW);

      digitalWrite(red_LED, LOW);

      digitalWrite(green_LED, LOW);

    }

    if (results.value == BUTTON_OK)

    {

      digitalWrite(blue_LED, HIGH);

      digitalWrite(red_LED, HIGH);

      digitalWrite(green_LED, HIGH);

    }

    if (results.value == BUTTON_1)

    {

      digitalWrite(blue_LED, HIGH);

    }

    if (results.value == BUTTON_2)

    {

      digitalWrite(red_LED, HIGH);

    }

    if (results.value == BUTTON_3)

    {

      digitalWrite(green_LED, HIGH);

    }

    irrecv.resume();

  }
