NEW GUIDE: Deluxe 4×4 NeoPixel Keypad @adafruit @johnedgarpark #adafruit
This new guide by John Park, Deluxe 4×4 NeoPixel Keypad, shows you how to create a high-end, custom keypad using NeoKey Ortho Snap-apart PCBs, mechanical keyswitches, keycaps, a QT Py, and an aluminum case.
You can create anything from a USB HID keypad, to MIDI controller, to music clip launcher using this design.
Code it in Arduino on the QT Py M0, or you could opt instead for a QT Py RP2040 and use CircuitPython as well.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
