A tiny MIDI controller with Raspberry Pi Pico and #CircuitPython
Sebastian builds a nine key MIDI keyboard.
With a MIDI library available for the Raspberry Pi Pico making a little MIDI “piano” is relatively easy. The MacroPad which I build last month is the perfect little device to play around with this.
If you want to follow along exactly, first you’ll have to build my MacroPad, though pretty much any Raspberry Pi Pico with a few buttons attached will do. Just make sure to update the code below so that the pins correspond with your hardware.
The Raspberry Pi Pico will need to run CircuitPython for this to work, my MacroPad already had this.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
