Keyes IR Remote Sensor

My Bluetooth Remote Control Robot kit also comes with a Keyes Infrared remote sensor and a command .

You’ll need to install the IR Remote library for this to work. You can get it from github – Arduino-IR. To install, just follow the instructions provided in the README file.

If you want, you can learn a bit more about the IR protocol in the Ken Shirriff’s blog (link below).

This sensor has three PINS, from left to right : GND (-), VCC (2nd PIN), SIGNAL (S).

Let’s connect this to the Arduino. The signal PIN connect to digital PIN 11 (If you choose another, please change it in the sketch below).

#include <IRremote.h> //include the library
//PIN
int receiver = 11;
IRrecv irrecv(receiver); //create a new instance of receiver
decode_results results;
void setup() {
 Serial.begin(9600);
 irrecv.enableIRIn(); //start the receiver
}
void loop() {
 if (irrecv.decode(&results)) { //we have received an IR
 Serial.println (results.value, HEX); //display HEX
 irrecv.resume(); //next value
 }
}

Here is the result, from pressing buttons on the remote:
