 * IR receiver simple test:

 * When pressing the TV button on the remote control or the other so that the infrared light blinks a few times

  / / Serial.println (ir_status); / / print the status irReceiver to Serial Port

  / / Check if there irReceiver receive infrared signals

  / / Yes, ir_status will be 0 (because the Receiver will signal the reverse, so 0 representatives receive signals)

  if (ir_status == 0)
