Story

This video discusses how to use IR Receiver with IR Remote.Infrared (IR) communication is a widely used and easy-to-implement wireless technology that has many useful applications.... With a simple IR transmitter and receiver, you can make remote-controlled robots, distance sensors, heart rate monitors, DSLR camera remote controls, TV remote controls, and lots more.

How to work IR Receiver?

An IR receiver can detect bursts of infrared light sent by a common remote controller (like for a television), and then output a pattern of high/low signals to a Propeller I/O pin.... Then, you will run a test program that will display the number for the remote button pressed in the Serial Terminal.

Code

Arduino code

#include <IRremote.h>;

IRrecv energen(11);
decode_results results;



void setup() {
  // put your setup code here, to run once:
 pinMode(4,OUTPUT);
 Serial.begin(9600);
energen.enableIRIn();
}

void loop() {
  // put your main code here, to run repeatedly:
if(energen.decode(&results)){
  Serial.println(results.value,DEC);
  energen.resume();
}
delay(100);
long val = results.value;
if(val==16236607){
  digitalWrite(4,HIGH);
}
if(val==16203967){
  digitalWrite(4,LOW);
}
}
