Wednesday, we'll start a mid-semester project: building an rpm sensor for a fan. Here is a rough description of the project and your expected deliverables. We'll talk about it more in class tomorrow, but it will be very free-form: I'll give you a problem to solve, a few suggestions, and see what you come up with (along with guidance along the way of course).
If you think about the last few labs we've done, and pay attention in tomorrow's lecture, a decent solution should present itself. You've already built all of the circuitry required as previous projects, the trick will be combining it all together. Similarly, you've already written the code you need (counting pulses), in principle. I have already done the project in one way, so it is workable using what we've studied.
I expect we will spend 3-4 lab sessions on this, but we'll go as long as it takes. Once this is done, we'll start longer projects of your own choosing, something that will take most of the rest of the semester to build up and fine-tune. (Maybe something like this?) Details on that to follow in a week or so ...
