Last night I was able to try out some code on the Vulcan Salute that seems to work. The LEDs, motor, and infinity lights were responding to commands from Jason Coon's Webserver app. I discovered that some of my LEDs are happy with a 3.3V data signal, and some LEDs are not. I got lucky, 2 out of 3 of my strands do not appear to need level conversion, but one does. It appears that the 12V boost converter requires a 5V signal. With a 3.3V signal, I could hear the inductor whining at the right frequency but it was not turning the LEDs off. The H-Bridge Motor controller also needs level conversion from 3.3V to 5V. Tonight I will try a cheap version of one of those level conversion boards based on the BSS138.
