opens door Badge.
With the approach of a card or a magnetic card reader of RDIF, a selinoide folds.
A green LED indicates that the door is unlocked 3 seconds.
Then the selinoide unfolds and locks the door.
If you pass an invalid card, a buzzer sounds and a red LED flashes (optional).
Indeed, if one program that maps the valid code, invalid cards will have no effect.
Since then, we can eliminate the buzzer and the red LED.
In order to enter the card code in the skit, the console is launched and it shows the code of each card.
A single power supply 12 volts.
