Relays_c_Delay

/*     http://labdegaragem.com/forum/topics/alguem-pra-me-ajudar-a-da-um-delay-500
  Relay IN1 connected to PinOut 2 Arduino
  Relay IN2 connected to PinOut 3 Arduino
  Relay IN3 connected to PinOut 4 Arduino
  Relay IN4 connected to PinOut 5 Arduino
  --->you can connected to relay modul 4 channel

  Serial data sending from Arduino Bluetooth Relay 4CH.apk
  data '1'-'4' to on is Ralay CH 1-4
  data 'A'-'D' to off is Ralay CH 1-4
  data '9' to on ALL CH 1-4
  data 'I' to off ALL CH 1-4
