What is Arduino®

Arduino® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a twitter message or publishing online. Surf to www.arduino.cc for more information.

Product Overview

The WPI300 is a simple keypad for entering user data into your project. Together with a library, it will allow your Arduino® to read a matrix type keypad.
This keypad features 12 buttons and is made of a thin, flexible membrane material  with an adhesive backing so you can attach it to nearly anything.
