Two-button Digital Lock

Published in issue 391, July/August 2009

Two-button Digital Lock
Here's a digital lock unlike any other, as it has only two buttons instead of the usual numeric keypad. The way it works is as simple as its keypad. One button is used to enter the digits of the secret code in a pulsed fashion — i.e. the number of times you press the button is determined by the digit to be entered!
