Hi there! As some of you may know, I have a bit of prior experience with Arduino, coding, and circuits, but these initial lessons were a really great refresher for me and helped me gauge my current level. I tried to add a few lines of code here and there (including for-loops, if-then statements, and arrays), and coded from scratch whenever I felt comfortable. Here’s what I got:
Add More LEDs
Here is a nice little sequence of lights.
It looks cool when you go a little faster.
Then I changed up the sequence a bit.
I wanted to this with all five LEDs. I tried couple of ways to do it… the one below definitely did not work.
I think it’s because I was trying to do some things with for-loops that I may have made too complicated. I simplified it to a nice, neat array below.
Here’s the plain circuit.
Then I put some newsprint over it to diffuse the light.
And then I cut a layer to make a somewhat creepy jack-o-lantern sort of thing.
And please let me know if you need help with your circuits! I am happy to help if you’re feeling intimidated. I promise it’s not as scary as my jack-o-lantern.
