Simple navigation keypad with a central 5-way joystick and two (left and right) buttons.
Can be used on a breadboard or integrated into your own PCB.
What You Get
PCB with optional components to solder. Fun and useful for both beginners and gurus.
Why did you make it?
I needed one but could not find it readily available.
Besides I just like writing software and learning new things.
What makes it special?
Highly usable yet simple to program and add to your project. The referenced sample Arduino code requires knowledge of C++. Yet the keyboard should be easy to use with any micro processor.
