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.
