PCB pin-headers 5V-GND-RST-10-11-12-13 allows to program the ATtiny85 from an Arduino UNO, instead of Arduino Nano. Remove from PCB any pluged Arduino Nano if you are going to program the ATtiny85 ...

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 ...

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 ...

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 ...
