Once I'm in the code, I'm good, but outside that is a lot of assumption and mystery. Is there something better for CAN bus programming than the world of Arduino?

Developers, engineers and Arduino enthusiasts may be interested in a new open source piece of hardware designed for CAN bus Arduino projects.

Before we dive into that project, let's quickly run through the basics behind the Arduino, and some of the various projects you can undertake using only other people's free, open-source Arduino code.

Arduino projects can be standalone or they can communicate with software running on a computer. The open-source Arduino environment makes it easy to write code and upload it to the I/O board.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...
