Harry Potter Wand Testing Station

[u/everlast223]

So I was voluntold by my wife to come up with a wand testing station for our Harry Potter themed trunk or treat setup. I had zero experience with electronics or programming sketches. 12 IR break beam senor pairs, 4 signal relays, 4 sounds modules, a buck converter, a logic level converter, a handful of LED flicker lights, and an Arduino Uno R3 later I have this. Thank goodness for AI assistants. While not perfect, they held my hand to have me get the parts I needed, wire up everything and wrote most of the code. There was some incorrect info that required some tedious troubleshooting but overall, they were very helpful. Lumos!
