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!
