Let's build something cool!

It is the supreme art of the teacher to awaken joy in creative expression and knowledge.
Albert Einstein

Arduinos

Everytime I want to build something I have to search the web for pinouts. Since the Arduino's claim to fame is simplicity and ease of use, that seemed counterproductive. So I finally decided to just put them on my own website where I knew where to go immediately. I will keep adding stuff to this page as time goes on. Pinouts as well as other relevant data.

Bare ATMega8 and Arduino NG and earlier with ATMega 8
