I designed and built a fully transparent Arduino UNO‑compatible board on a flexible PCB; no copper pours, no hidden layers. This is a fun project where you can literally watch the electrons flow (okay ...

YouTuber “EDISON SCIENCE CORNER” has designed yet another Arduino UNO clone but with a twist as the board is made out of a flexible PCB. Companies like JLCPCB, PCBWay, and others have been offering ...

Thanks to jaromir-sukuba, and racerxdl for working on firmware to implement C2 protocol via arduino GPIO. This work largely pulls from them, as well as connorpp. C2 is a 2-pin protocol. Any arduino ...
