Electronics and Programming for All
From alan-parekh.com: Single Button Code Entry System
Forget keypads and RFID tags, the guys over at alan-parekh.com have come up with the simplest possible user interface for a code entry system: a single button. Sold in kit form via their online store and incorperating a PIC 16F628A microcontroler and relay, this kit allows you to program and input a four-digit code using only one button.
Details and a video explaining how the kit works can be found here.
