## Article

We can use cayenne as remote controller for television or air conditioner.

Only one device can remote all TV/AC, more simple and can develop to other project by trigger. Example, if we enter the room then air conditioner can ON itself and if we out the room it's OFF automatically.

In my case I use Cayenne because it's simple for me.

## **Code

### UniversalRemote.ino

C/C++

```
#include "CayenneEthernet.h"
#include <IRremote.h>

IRsend irsend;

char token[] = ""; //fill with your token

void setup()
{
  Serial.begin(115200);
  Cayenne.begin(token);
}

void loop()
{
  Cayenne.run();
}

CAYENNE_IN(V3) { // send volume -
  for (int i = 0; i < 3; i++) {
    irsend.sendNEC(0x20DFC03F, 32);
    delay(40);
  }
}

CAYENNE_IN(V4) { // send volume +
  for (int i = 0; i < 3; i++) {
    irsend.sendNEC(0x20DF40BF, 32);
    delay(40);
  }
}

CAYENNE_IN(V5) { // send program +
  for (int i = 0; i < 3; i++) {
    irsend.sendNEC(0x20DF00FF, 32);
    delay(40);
  }
}

CAYENNE_IN(V6) { // send program +
  for (int i = 0; i < 3; i++) {
    irsend.sendNEC(0x20DF807F, 32);
    delay(40);
  }
}

CAYENNE_IN(V7) { // send power on/off
  for (int i = 0; i < 3; i++) {
    irsend.sendNEC(0x20DF10EF, 32);
    delay(40);
  }
}
