The most important lesson I learnt (from experience) when testing is to ensure cables are secure so they can't touch, connections are clearly labelled/colour coded/proper sockets fitted.
It is so easy when swapping boards & connections to make a wrong connection & let out the magic smoke.

This is how new I am to electronics- what are those plastic circuit board looking things towards the back and how can I use them? Are they basically like solder free PCBs (i.e. put wires in on top and connect them on the bottom?)
Thanks for the advice.
The white plastic things are breadboards. They are rows of something similar to an IC socket. Underneath they are connected together along the rows. You can poke component leads in a row and connect them together that way. As in the example.
Google "electronic breadboard" and see many.

Yes. also known as Protoboards.
Very useful for experimenting, but connections are somewhat flimsy, so a clever company
https://www.adafruit.com/product/571offers matching protoboards and exact same layout PCBs, so it´s easy transferring experimental designs to a properly soldered board without extra "thinking" or designing, just transfer parts pin by pin.
Push-in protoboard at right, top and bottom views of solderable PCB at left and center.
Stroke of genius.
They have printed "mapping" letters and numbers to make it easier,.
Great idea.
They also offer 3 board packs so you can keep using that smart idea.
Or need multiple copies of your successful design:

And the wires are 1/0.6mm Solid Equipment Wire which pushes straight into the proto board.

Even better are the ready made jumper cables:

Yep, that's some clever stuff there. Someone must have been sitting there looking at their breadboard and Ding! Light-bulb moment.
Love it.
