int avoidSensor = 2;
int lastAvoidState = 1; // 1 means clear, 0 means covered

void setup()
{
  Serial.begin(9600);
  pinMode(avoidSensor, INPUT);
}

void sendOnOffSignal() {
  for (int i = 0; i < 3; i++) {
    irsend.sendRC5(0x84C, 12);
    delay(40);
  }
}

void loop() {
  int avoidState = digitalRead(avoidSensor);

  if (avoidState != lastAvoidState) {
    lastAvoidState = avoidState;
    sendOnOffSignal();
  }
 
  delay(1);
