1. Adafruit Membrane 3x4 Matrix Keypad + Extras [ADA419]
Feature
Adafruit Part Number: 419Stock Type: Sensors >> Touch
In Stock & Ready to Ship
Description
Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 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.
2. Adafruit 3x4 Phone-style Matrix Keypad
Feature
Adafruit Part Number: 1824Stock Type: Sensors >> Touch
In Stock & Ready to Ship
Description
Hey, Jenny, I've got your number! And I'm going to dial 867-5309 into this very nice phone-style matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. It's made of plastic with sturdy plastic buttons. The keys are connected to a matrix so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.
There's a great Matrix Keypad Arduino library that should work great with this item with minor adjustments. It's basically a sturdier version of our Membrane 3x4 Matrix Keypad and comes with 7 or 8 header pins pre-soldered on for easy plugging. Starting from the left there are three column pins, and then to the right are the four row pins. If yours has an 8th pin, its not used and you can just leave it disconnected

5. Arduino Keypad Shield with 16-Button Matrix Keypad
Feature
Quickly and easily add a keypad to your Arduino project. Just plug it in, link the included Arduino library, and call getNextKeypress() to get each keypress!Mount the keypad directly to your Arduino (hardware included), or use the enclosed RJ45 adapters with your own Ethernet cable to mount the keypad remotely, anywhere!
The shield has stacking headers so it's easy to add another shield or access any of the Arduino's other pinouts to integrate the keypad with the rest of your project.
The shield uses only two Arduino pins (SDA and SCL), keeping the Arduino's other digital and analog pins free for the rest of your project. (16-button keypads normally require 8 pins; the Lectrobox shield has its own onboard ATTiny processor that talks to the keypad for you.)
The shield never misses a keypress, even if your sketch is busy doing other things. (Again, this works because the shield has its own tiny processor that does nothing but scan the keypad.)
Description
Whether you're giving your front door an electronic deadbolt, putting a combination lock on a puzzle box, building a novelty oversized calculator, or adding a launch control panel to your rocketship, there are lots of uses for a keypad in DIY projects! This hardware and software package gives you everything you need to easily attach a high-quality keypad to your Arduino with all the electronic, mechanical and software complexity made simple.
For maximum flexibility, the keypad can be attached to the shield in two ways. First, it can be mounted directly on the shield. Mounting hardware is included. This is a fast and convenient option that keeps the Arduino, shield, and keypad all together in a single unit. Second, it can be mounted remotely. Sometimes, the Arduino and Keypad may need to be in different places-for example, you may want to mount the keypad on the front of a box or next to a door and keep the Arduino itself somewhere else. In this case, attach the included RJ45 dongle to the keypad and connect the keypad to the shield's onboard RJ45 jack with any Ethernet cable.
The keypad itself is high quality, rated for 1 million keypresses and with satisfying key travel. This isn't a cheesy membrane keypad!
