4/3 - 4/5

This week I worked more on code, I finally got the Breakbeam sensors to work with both the pins on the metro mini and the multiplexer, as well as using a display to show the number of sensors that have been activated. To do this I had to restore my code to an older version and add the multiplexer code one line at a time, in order to ensure that it wouldn't stop it from working. I also got the code to work with up to ten sensors, and even though I'm only using six sensors now, I will have more than that in the final product.

I also planned on finishing the PCB this week, but Fusion 360 wasn't working with PCBs or schematics so I was unable to finish that.
