My experiences are of course not compatible with todays school curriculum but I can't see this as a first-year project.
Remember that the first year, the students are busy with basic courses. A lot of math and other courses but also initial analog and digital etc. And they should also have had time with microprocessors/controllers, knowing how to debounce keys, send/receive data on serial ports etc. And while you can break it down into many small and simple steps, the total number of steps will require more time than the students would have available during the first year. Now perhaps today's students aren't up to the level of effort that I think of in terms of first-year projects, but this one lacks much of the challenge to which you refer, Per. There's so much information available today, if the first-year student simply searches for it, that matters such as the sending and receiving of data via the serial port, and debouncing keys wouldn't have much impact. This exercise, as I see it, is simply a counter and a table-lookup, leading to a straightforward output routine. The only circuits challenge lies in directing the appropriate current through each of the LED's. Do you think that's particularly difficult? While there is a bit of arithmetic, there's no math. I'd guess that the real challenge for a first-year student, in this context, is in demonstrating the diligence and discipline to get the job done. I'd point out that I see students almost every day, even on weekends, as I frequently have 'em in my employ. They're not all as lazy as most of 'em. RE |
