Description
Product Description
Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, 
arranged in a telephone-line 3×4 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 7 microcontroller pins
 (3-columns and 4-rows) to scan through the pad. Check the tutorials tab for links to 
an Arduino library and example code.
We include a 7-pin extra-long header strip so you can plug this into a
breadboard with ease.
  • Weight: 7.5 grams
  • Keypad dimensions: 70mm x 77mm x 1mm (2.75″ x 3″ x 0.035″)
  • Length of cable + connector: 85mm
  • 7-pin 0.1″ pitch connector
There is a very nice Matrix Keypad Arduino library that works great with this item. The only thing we suggest is to change the initialization code in the examples to this:
#include "Arduino.h" #include "Keypad.h" const byte ROWS = 4; //four rows const byte COLS = 3; //three columns char keys[ROWS][COLS] = { {'1','2','3'}, {'4','5','6'}, {'7','8','9'}, {'*','0','#'} }; byte rowPins[ROWS] = {8, 7, 6, 5}; //connect to the row pinouts of the keypad byte colPins[COLS] = {4, 3, 2}; //connect to the column pinouts of the keypad Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
