the circuit
You know the drill ...
This one is like the previous LEDs, only more so.
the code
The code, like last week, introduces several
new ideas, mainly arrays. We'll go over 'em in class.
variations
What other sequences of which-one-lights-up-when can you do?
Can you add a potentiometer and have the lights act
as a meter (i.e. more lights when it's turned further)?
For those of you who already know how to code :
can you have the lights give the potentiometer value in binary?
How about an arrangement of LEDs that is
in a grid rather than a line? Is the circuit
practical on the breadboard? What patterns might
you do then?
future
Discuss :
There are 16 labs and 13 weeks, so we're going to have speed up if we're going to get through them all. Either we can divy them up and do some show-n-tell, or just do several per class. Your thoughts?
I would also like to have you write-up a couple, say one before spring break and one at the end of the term. Let's discuss in class.
Your thoughts?
