Garage Door Keypad

Remote garage door openers are great but there were times I need access to the garage and did not have the remote with me. I therefore designed a simple keypad with 4 digit access codes to allow myself, my family and friends to gain quick access to the garage when a remote is not at hand. The hardware consists of a 4x4 keypad, a 5V pro mini Arduino, a small custom PCB and a few external electronic parts to complete the design. The software is in an Arduino sketch. You will need to the Arduino IDE if you do not have it.”
