Introduction

IR Transmitter Module is designed for IR communication which is widely used for operating the television device from a short line-of-sight distance. The remote control is usually contracted to remote. Since infrared IR remote controls use light, they require line of sight to operate the destination device. The signal can, however, be reflected by mirrors, just like any other light source. If operation is required where no line of sight is possible, for instance when controlling equipment in another room or installed in a cabinet, many brands of IR extenders are available for this on the market. Most of these have an IR receiver, picking up the IR signal and relaying it via radio waves to the remote part, which has an IR transmitter mimicking the original IR control. Infrared receivers also tend to have a more or less limited operating angle, which mainly depends on the optical characteristics of the phototransistor. However, it’s easy to increase the operating angle using a matte transparent object in front of the receiver.

irsend.sendRC5 0x1, 8 delay 200 ;
• Upload code to the UNO connected with IR Receiver:
#include <IRremote.h>
const int RECV_PIN = 11 const int LED_PIN = 13;

IRrecv RECV_PIN ;
decode_results results;
void setup

Serial.begin 9600 irrecv.enableIRIn // Start the receiver
void loop
if irrecv.decode &results
if results.bits > 0
int state if 0x1 == results.value
state = HIGH else
state = LOW;
digitalWrite LED_PIN, state ;
irrecv.resume ;
// prepare to receive the next value
