A project assemblying a servomotor to move the lock, Ir Receivers (one for each side of the door!), and an Arduino Uno as controller. Buzzer, because beeps are cool.

Small project for a discipline in college. It's just a servo moving a lock device after the Ir Receivers receive a password, that is read for Arduino. Beeps are always cool.

 

The code have some pt-br words, but nothing that a google translator can't solve.

 

The code is the last stable version i've made. Fell yourself confortable to edit it as you heart desire.
