Do you need an LED? The answer is always yes. But what if you need one right now? Build yourself an LED gumball machine and never run out again!
This machine was created for the CU BTU lab because students constantly needed LEDs but filling parts bins always seemed to fall to the tragedy of the commons. We’d put 1,000 LEDs into the bin and they’d be gone in less than 2 weeks. With the Gumball LED dispenser the LEDs last for more than a semester. It’s amazing how much a 15 second pause will cause people to think twice.
This repo is the software that runs on the Gumball Machine. You can read the full tutorial here.
