A binary keyboard for programmers by @workshopshed in Issue 18 — HackSpace magazine #Making #ItsyBitsy @HackSpaceMag
Build a binary keyboard for programmers! Andy Clark shows you how in Issue 18 – HackSpace magazine.
The secret to creating a keyboard controller is to use a microcontroller such as the ATmega32U4 (Andy uses the Adafruit ItsyBitsy Microcontroller board – so tiny, so useful!) featuring built-in USB capability. There are different classes of USB devices such as disk drives, keyboards, and sound devices. To act as a keyboard, the microcontroller shares the classes it supports with the host computer – it can then communicate using the standard drivers built into the operating system.

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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
