This is great, I've tried playing with Arduino a bit in the past, but didn't have a real understanding of what I was doing.<p>On the flip side, I still struggle with most of these arduino or RaspberryPi "make hardware" stuff, because I don't understand what the next step is after I make the prototype for myself. Are we expected to build on top of an Arduino or RaspberryPi? Do we have to then port our designs to a custom platform? Hopefully the course will answer these questions.
