Keypad Security Door Lock
I just finished my Keypad Security Lock project a week or so ago, which I’ve been working on and off with a break in the middle for the past few weeks now. Held together with sticky pads and hookup wire, I present my latest creation:
(excuse the shoddy camera angles, it’s tricky to hold the camera and type when the keypad is on the other side of the door!)
Components:
ATmega 328P
Strip board
ABS housing
Full rotation servo (why did I get a full rotation one…)
Reed switch and magnet pair (to accommodate for the decision above)
3×4 matrixed keypad
240v -> 0.7A 5v mains transformer
ribbon cable, hookup wire, resistors, etc.
