Move up Delete Move down

Process

Describe the process you underwent to reach the outcome (problems encountered, how you resolved them, as well as, experiments, hacks, tests, refinements, iterations, failures)
A LOT of things went wrong with this project. All my issues revolved around the circuit.
I created the first circuit on my bigger breadboard first. I ran the code, and fixed wiring left, and right to figure one side of the breadboard's ground aisle was not working. This breadboard kept giving me problems, so I switched my circuit to the smaller breadboard that comes with the original particle.
After switching to the smaller breadboard, I realized that the components were working, but the LED was not as bright as it should be. Since this is a smaller breadboard, I could not catch that the wire connected to 3V3 had undone itself. After that was fixed, everything was working wonderfully.

Reflection

Reflect on the process of doing this project. What did you learn? What would you do differently?
The main thing I learned is that having an efficient troubleshooting process can save you a lot of time. When trying to realize what was wrong with my bigger breadboard, rather than testing the ground cable first, I just ripped everything off the breadboard and then tested the ground cable.
