I bought a couple displays before the one I settled on, then a couple after (well same display but paired with an ESP32). I had bought some toggle switches originally but didn’t end up going that route. Bought some breadboards that I could put together because the ESP32 devkit doesn’t fit on a single one. Bought a battery and some other random things. Almost bought a different joystick to try. I probably should have stopped buying things awhile ago. 
Oh well, it’s fun and I can use the things I’m not using in other projects.
