A week ago dcoslet asked for the source code of the Arduino WS2812 demo I uploaded here 3 years ago. Took me a while to find it again, but nothing ever gets lost! Since I don’t think it’s worth a GitHub repository, here the code: testleds.zip
Recently for an initiative of my workplace I was looking for a programming course for children. Think “Hour of Code”, but make that 3 hours and “real” programming. “Real” programming means: typing code and getting potentially syntax errors. Target age bracket was 11-14 years old (Junior High School in Japan).
Greg was kind enough to merge my changes, so anyone can now relatively painlessly add more languages.
