gatekeeper for arduino

This program was created to inform if the house gates (main gate and garage gate) are open.
The information is printed on the standard LCD 16x2, also when any of the gates is open, it beeps with buzzer.

Version 1.1 includes screensaver in order to prevent burn-in lcd screen.

Inputs:

Outputs:

• Pins: 12, 11, 5, 4, 3, 2 - LCD
