RESULT

  • Door locks when it's dark outside, if a vehicle departs from the garage, or when the star (*) key is pressed on the keypad

​

  • Speaker plays distinct sounds for correct and incorrect numeric sequence entry and when the lock actuates

​

  • LCD display shows current status of the system and the keypad numbers that have been pressed


  • LED strip surrounding the control box will initiate as various colors depending on the status of the system
