Keypad - 12 Button

3.5 €3.50

Availability: Retired

A basic 12 button keypad for user input. The buttons are setup in a matrix format. This allows a microcontroller to 'scan' the 7 output pins to see which of the 12 buttons is being pressed.

There's not a really good tutorial out there on button pad matrix setups! Sorry about that. We should write one...
