Here’s a great booklet to accompany any new Freeduino purchase - “Getting Started with Arduino”, written by Massimo Banzi (the co-founder of the Arduino Project).
This title is based on his free-download introduction PDF, but takes is much farther, guiding new electronics enthusiasts into how to use the Arduino / Freeduino in a project.
Also cool is this little link we just received the other day from a customer of ours, Gary Gipson. Our book “Junkbots” was put to good use with this project! Instead of stationary electronics, these electronics swing! (Plus, it’s darned cute!)
