March 28th, 2008 Electronic combination lock with AT90S2313 or ATtiny2313
Electronic combination lock always fascinated me since i was a kid, playing with blinking LED circuits. At that time i was always thinking on some sort of electronic combination lock that i could add to my bedroom door, but unfortunately i wasn’t working with micro-controllers at that time so it was very difficult to put together something like this. But these days you can easily build a project like this, the parts are available everywhere.
