Build and customize your very own open-source button grid controller based on the Adafruit Trellis with the OONTZ kitHELLA OONTZ KIT! Designed by PaintYourDragon, this DIY kit comes with delicious translucent button pads, controller pads, diffused white LEDS and a custom laser cut enclosure. The result is a sturdy, BIG, and elegant but also super-hackable music or video (or something else???) controller device.
We designed this kit for ease of use and ultimate flexibility. All you need is an Arduino Leonardo, basic soldering tools and an afternoon. Once assembled and programmed with the Arduino IDE, this box turns into a USB MIDI device that works with any computer and has 128 buttons with controllable LEDs. Our default example program sends a MIDI Note On and Off message for each button press but with a little programming ingenuity you can send and receive any kind of MIDI command. Since its USB MIDI it can work instantly with just about all synth software. Don’t like MIDI? The Leonardo can also emulate a USB keyboard or plain old USB serial.

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.
