Product details of Flexible Keypad 3×4

  • 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 );

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
