I made a list of blue and yellow boards problems by poking about with an ohmmeter. The issues weren't identical, which means the problem isn't incompatibility with a makeshift shield. I did my best to fix them, and one worked fine, but the other still needs work.
I looked at my incomplete distance sensing code for the ultrasonic device and programmed the controller to change light intensity as things moved. The light changed accurately, but it also flickered. Since there wasn't a serial reading, I couldn't tell what was happening accurately. I swapped in an Arduino Nano to get numerical data and looked at the plotter to get an idea of how to approach the idea of starting a timer when someone crosses a line. I scribbled some pseudo-code to determine the area of interest and activated the onboard LED whenever something closer came into view.
The light goes on when my hand crosses the beam
