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.

Check the examples below for correct pin-outs and such.

 

The grid laid out like this :

 

  3    1    5

---------------

|  1    2    3  |       2

|  4    5    6  |       7

|  7    8    9  |       6
