Pimoroni Pico RGB Keypad base
/This is a nice little add-on for a Raspberry Pi Pico. It’s a hex keypad with very pretty illuminated buttons. It’s easy to set the colours of the buttons and read their state into a Python program (not tried C++yet).
I’m very tempted to move the two button game onto this platform, I think it would work rather well. You can get the kit from here. Remember that you’ll need a Raspberry Pi Pico to plug into it as well.
