  • Keypad Shield with 16-Button Matrix Keypad for Arduino
    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.)
