DESCRIPTION

Punch in your secret key into this numeric matrix keypad. This keypad has 20 buttons, arranged in a telephone-line 4x5 grid. It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 9 microcontroller pins (4-columns and 5-rows) to scan through the pad. Check the tutorials tab for links to an Arduino library and example code.
