Ohhh it works? 😯
4.96V is pretty bloody close to 5V considering this is just a breadboard and I've wired the switch and DC jack using just whatever the wiring that came with that electronic advent calendar is. Not actually soldered on, obviously. I reckon this'll be a solid 5V when it's an actual PCB.
Also I accidentally ordered the tiniest little switches and I'm not even sorry! 😆😁
