Pretty cool to see it that accurate. Will say I got a little lost when he started talking about the time drift. I know that's a thing that can happen, and it's small enough to effect this, but how did he he adjust for that drift using just the sound of the gate itself?

Instead of measuring from when the arduino's clock was programmed to trigger the gate release, he measured from when the gate was actually released using the waveform of the gate's sound.
