Hi
I did this before posting my last message and processing show me in black window that COM1 on position 0 and COM2 on position 1 are available. i modify my program with "Serial.list(),[1]" and i run processing.i have no result, my strip led doesn't light. I try every COM port with concordance with arduino software option and nothing.
My strip led light with arduino software but nothing with processing
See you next post
