This one has been a long time in the making for two reasons. First, I spent some time creating an opening sequence for the videos. Thanks to everyone who helped me decide on the right music to use.
Secondly, because this is a topic which comes up all the time. What is the difference between an Arduino and a Raspberry Pi?
Often people pick one because of (perceived) popularity or because of price, or because of raw specs. When it comes down to it, you really have to decide how you're going to use it.
So, enjoy this video which compares the Arduino to Raspberry Pi.
