and this keeps looping
the stored files are from another sketch btw… the one wich can record and play 4 universes on an esp8266.
That did work for now… next step was to merge some code from that sketch into yours (button configuration) and try it …
really need to read and study more code…but it’s to hard to understand it all right now .
i’ll get there one day…
