I missed last week because I was out on Friday. But last week and this week major progress was made.
I got the magic tube completed.
The stoplight rewritten code has also been completed, uploaded to the physical stoplight, and is committed to Github.
I'll put the code here if you'd like to read.
/*
Replace the total with sizeOf in the for loop
Move the period type out of the conditional

}It's about a couple hundred lines of code but it is much better than the old one.
