Summary

This wraps up the basics behind some of the fun stuff that can be done in an analog world that consists of more than just on and off. You should have a pretty good grasp on how to read an analog sensor, and use these readings to change the brightness of an LED or adjust the speed of a motor. We also talked about how to see these numbers and once you know what they are, how to manipulate them into forms that are more useable for one purpose or another. For a little more information on this subject, you might also check out some of the example analog sketches included with the Arduino programming environment.

For now we are going to move on to a more advanced discussion of functions that includes some functions we haven't discussed before; ...
