Getting an Arduino and a Raspberry Pi to communicate

Went through an exhaustive process of trial and error learning various ways to get an Arduino and raspberry pi talking to one another. After successfully figuring it all out, I had a failure with some plastics and silicone. This failure turned into a goopy mess, but I was able to salvage it partially… next time I’ll solder it instead.
