[Dragonfly DIY] Arduino blocks lesson 2 - switches

Switches are pretty important to learn, they're the main method you'll use to control many projects.

As part of this lesson, we'll learn about schematic diagrams. Don't be scared, all they are is a way to doodle electronic ideas before building them.

I really recommend doing this lesson on the video. It's largely programming instruction and that comes across best on the video.

[Dragonfly DIY] Arduino blocks lesson 3 - Analog inputs and serial debugging

In this lesson I'm covering two things - inputs that are analog, that is, not just zero and one but a whole range of values, and also serial debugging, which is a simple technique that is very helpful in getting small programs and circuits working before going on to bigger things, and also in figuring out "what the heck is going on" inside the Arduino sketch.
