<p><strong><span style=”font-size:18px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>Description</span></span></strong><br />
<span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3×4 grid. It&#39;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 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.&nbsp;</span></span><br />
