Good tutorials after ladyada.net (including coverage of capacitors, transistors, etc.)?
I've made my way through the Arduino tutorials on ladyada.net, and I'm now having difficulty selecting good materials that progress from there. Any tutorials or books you would recommend?
I got the book "30 Arduino Projects for the Evil Genius". It has some interesting projects, but it doesn't always explain the theory behind the circuit design as much as I'd like. In particular, it would be nice to find more detailed treatments of capacitors and transistors.
