AWOL;
ok I'll try to rewrite the program and put everything in little boxes (arrays). First I wanted to check if the program worked and I thought of doing this later on (to rewrite it in a nicer way), but then it desyncronized so fast I thought something must be wrong.
KE7GKP:
It is not clear whether this is just an abstract, generic, academic exercise or whether you are trying to ELIMINATE this gradual loss of sync, or maybe whether you are trying to PROGRAM some gradual randomness?
I am really trying to eliminate the loss of sync. But the reason I want this is purely holistic, I often need millis() and am in a learning process about them, this program for me is an introduction. I don't need those synced LED's themselves, but I need the knowledge to get them syncronized since I always need syncronized things ; )
thanks
