Punch in your secret key into this numeric matrix keypad. This keypad has 16 buttons, arranged in a telephone-line 3x4 grid + 4 extra keys - A, B, C and D. 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 8 microcontroller pins (4-columns and 4-rows) to scan through the pad.

Check the resources at bottom of this description to get the tutorial and sample code for Arduino.

Note: You might need extra long header pin or jumper wires so you can plug this into a breadboard or Arduino with ease. Check this video by Gadget Reboot:
