/*
  Input_Output
  This program is to simplify your morning routine. It uses a light sensor to detect when the sun rises, a water sensor to monitor the water level of the plant-pot, and a servo motor to open the dog's feeding bowl. Also, it plays a morning song and sends a "Good Morning" email to start your day better.

  The circuit:
  input devices - Light Sensor, Water Sensor, DHT11 Sensor
  output devices - Servo Motor, WiFi connection
