2022-03-05 (Sa) RemoteFinishLine More real-world testing

I was worried about the erratic behavior at the gym last time, so I brought the hardware in again. I thought the problem was with mistakenly sensing an echo near the sensor. I fixed that issue by ignoring reads that timed out and returned a zero. I changed the program to print continuous distance readings until I pressed the button, then it would act like usual. The maximum distance was about two meters which I estimated by lying on the ground and adding a bit. The readings looked steady when I pointed at a wall, but I asked a few folks to walk in front of it, and like me, they waved their hands as fast as they could. When someone walked in front of the camera, we discovered that the distance sensor couldn't detect clothing well. I hypothesize that the soft, uneven surfaces absorb and scatter the sound waves instead of reflecting them. I will have to figure out a different sensor.
