The software serial port was reassigned to use the pins right next to the power pins so the Bluetooth module could be plugged in without relying on a cumbersome wire harness.
For a few iterations, the addressable LED strips were not working. This seemed like a problem with the hardware since the power wires rested inside a couple of pads without solder. Header pins were installed behind the USB socket, but they remained off. The problem seemed to be a lack of memory in the ATMEGA328P chip. It seemed to be gobbled up by the NeoPixel library, but there was no notification. 900 lights are needed for the final project, and trial-and-error testing showed the limit to be near 450. This did not include writing each of the colors to a register in the controller for use later.
A three-strip array was built to test if the controller could simultaneously control them. The idea was that a strip of 900 was too long of an array but three short arrays would be acceptable. When the LED array was built, it used the mating devices so it could attach to the board easily and come off for the final build.
