Electronics, explained one circuit at a time. Written guides to every DigiCirq video.

DigiCirq is a faceless, diagram-only channel: short animated explainers on how electronics, Arduino, microcontrollers and the apps on your phone really work. Each post here is the written guide to one video, with the numbers worked out and something to try on your own bench. Videos: youtube.com/@digicirq
