Lab 6 will be less of a formal lab and more of an introduction to the Arduino and preparation for a final mini-project. The lab handout has a few questions that should be answered and turned in to get credit for this lab, but most of the information is contained in the series of tasks contained on the web pages linked below. While it isn't strictly necessary, I would encourage you to work through these tasks in order. In particular, you should start with the Arduino IDE page as soon as possible and make sure you can communicate with your Arduino Nano board.
I have some other pages that I have used in labs in the past. I have left these here as they may be interesting as possible project ideas.
