HackSpace Magazine Issue 48: Make an isomorphic keyboard with Pico #PiDay #RaspberryPi #CircuitPython @HackSpaceMag
HackSpace magazine issue 48 demonstrates a project to make an isomorphic keyboard using a Raspberry Pi Pico programmed in CircuitPython.
Last month we showed you how to make a switch matrix and enclosure for an isomorphic layout keyboard. This month we will finish the construction, and look at the Pico board, control switches, OLED display, and rotary encoder, as well as how to wire it all together. We will also look at the software we need to test what we have built, and the final software to bring it all to life.
We decided to use CircuitPython from Adafruit, having used MicroPython, and C in our previous two projects. It had the big advantage of having a USB MIDI capability.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
