New Guide! Lemon Keypad with QT Py RP2040 @ecken @videopixil

DIY USB-HID With a Twist of Lime
Make a custom USB-HID keypad in the shape of a citrus fruit. This keypad features six mechanical switches for controlling media players like Spotify, iTunes, YouTube, etc. Powered by the Adafruit QT Py RP2040 and CircuitPython.

Inside the case is a NeoPixel Jewel that slowly fades in and out making the keypad illuminate. The QT Py and NeoPixel are housed in a 3D printed case with part that snap fit together.

Lemon, Lime and Fruits
The case and key caps can be 3D printed in different colors. Choose a color scheme that best matches your preferred flavor of fruit. Could it be an orange, a lemon, a lime or maybe a watermelon? You decide!

Kailh Mechanical Key Switches
Click, click, click… Mechanical key switches offer a tactile feeling and there’s a few varieties of switch type. Choose the type that best suits your preference.

Custom Keys

One of the goals of this project was to create a unique layout for a keypad. Originally conceived as a circular keypad, the enclosure evidently turned into a fruit inspired shape. As a result, the key caps are cute little triangular pieces.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!




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.
