If you're still hanging on after some of that less-than- friendly code, then good for you. Anytime I have to dredge through any of that fringe stuff that hasn't already been brought into the Arduino fold, I am plenty thankful for everything that has already been wrapped up for us. Arrays are a pretty useful tool in our Arduino projects and we could use two chapters to get through everything that can be done with them, but we still have more things to talk about. Arrays work to make all manner of lists of things from pin numbers, to output levels, sensor readings, and even text messages. They can be rolled into loops and functions with amazing ease because of their indexed data elements. We just need to be careful how we handle our memory ...
