Arduino Port Access & Bitwise Op. using Simple Robot Controller

In this article, we look at how to access an Arduino port to read or manipulate a group of pins in C code. We use bitwise operators to read, set and invert bits in variables and device registers. To help with this feature, we will use a simple robot controller to demonstrate how we might use port manipulation. I include, for example, Arduino test code and illustrations of bitwise operations.
