Keypad based garage door access

Keypad based garage door access

Garage is one place that need to be protected but also has to be convenient to access. When driving in and out a remote control is great choice. SamJBoz had a problem with his remote control so he decided to build in a keypad controlled system based on arduino.

Keypad system uses 4 digit pin codes for opening lock. Each family member has its own pin code. User with master code can enter and delete new users. Arduino Pro Mini sits on a custom PCB which has necessary connections for keypad, Piezo buzzer, LED and other. Eagle files are available for download.
