Ir remote control repeater?

Other Hardware Home Automation
1

I'm interested in know how to build an remote control range extender or repeater for home or office use. Do you have any idea how to code it?

There are lots of Google results for Arduino IR repeater.

Hi!

This code works for me.

//Código que repete os sinais dos controles do projetor e do receptor de TV.

#include <IRremote.h>
#include <IRremoteInt.h>

const int RECV_PIN = 2;
const int STATUS_PIN = 13;
const int RELAY_PIN = 4;
const int SENSOR_PIN = A0;

IRrecv irrecv(RECV_PIN);
IRsend irsend;

decode_results results;

bool relay_state;
unsigned long millis_temp;
float desired_tempeture = 40; // Temperatura desejada para acionamento do ventilador.

/*
  // Storage for the raw data
  unsigned int rawCodes[35];
  int codeLen;
*/

void blink()
{
  digitalWrite(STATUS_PIN, HIGH);
  delay(100);
  digitalWrite(STATUS_PIN, LOW);
}

void check_temp()
{
  float temperature = (analogRead(SENSOR_PIN) * (4.11 / 1024) * 100);

 // Serial.println(temperature);

  if (temperature > desired_tempeture)
  {
    digitalWrite(RELAY_PIN, HIGH);
  }
  else
  {
    digitalWrite(RELAY_PIN, LOW);
  }

}
/*
  void extractRaw (decode_results *results) {
  codeLen = results->rawlen - 1;
  // To store raw codes:
  // Drop first results.value (gap)
  // Convert from ticks to microseconds
  // Tweak marks shorter, and spaces longer
  // to cancel out IR receiver distortion
  for (int i = 1; i <= codeLen; i++)
    if (i % 2)
      // Mark
      rawCodes[i - 1] = results->rawbuf[i] * USECPERTICK - MARK_EXCESS;
    else
      // Space
      rawCodes[i - 1] = results->rawbuf[i] * USECPERTICK + MARK_EXCESS;
  }*/

void setup()
{
//  Serial.begin(9600);
  //Serial.println("Hello!");
  pinMode(STATUS_PIN, OUTPUT);
  pinMode(RELAY_PIN, OUTPUT);
  pinMode(SENSOR_PIN, INPUT);
  irrecv.enableIRIn(); // Start the receiver
}

void loop()
{
  if ((millis() - millis_temp) > 60000UL)
  {
    check_temp();
    millis_temp = millis();
  }

  {
    blink();

    }
    irrecv.enableIRIn(); // Re-enable receiver
  }
}

Best regards.

Yeah. But some of them are incomplete and doesn't work correctly

Thank you. I will try it

Try starting one, then you can ask for help if you run into a specific issue.
