I made a red LED flash. The next project was to make a series of 8 LEDs flash – in sequence up and then in sequence down. The programming for this was still simple. It got more complicated when I was playing with the code to make just the green LEDs flash, then just the red. I reprogrammed to all the lights come on, in sequence, then go off again in sequence. That coding was a little more challenging.
Still, I am learning a bit about circuits and I guess I am halfway back to remembering how to code in C.
Next project I think will have some switch built in, so that I can turn the thing on and off. Each of the circuits gets just a little more complicated as does the coding so it is a good learning process.
And now … watch the little lights flash.
