Newbie Arduino challenge

[appv128]

Hello, I saw a few other posts mention a similar problem but did not see a solution. Apologies if I missed it.

When I hookup my pc to Arduino which is already running the basic victor_ sketch in random mode and start Vixen, the random mode shuts off but does not respond to the sequence being streamed. The only way I have been able to get it to start is by uploading the sketch again use Arduino IDE and then starting Vixen immediately at which point the board responds to the sequence.

Appreciate any inputs on what I might be missing. Thanks.


Setup : PC >> Arduino Mega >> 6 Sainsmart SSR

Thanks Kevin, my Arduino is on light sensitive switch that turns on earlier and I usually turn on the pc manually a little later. Will try changing the order to shutoff the Arduino before starting the PC up and see if it addresses the issue. I thought that as the random mode shut off the pc was communicating with the Arduino board.
