There are two objectives to this assignment: soldering a circuit and connecting it to the Arduino, and creating two digital input/outputs from the Arduino to the breadboard.
Part 1: For the first part of the project, I needed a prototyping board and materials used from the first project. The objective was to get a circuit from the previous lab (basic electronics) and build it on the prototyping board. Then, the PCB would be connected to the Arduino and breadboard with a maintained switch.
This is the schematic of the PCB

It was my first time soldering, and it took very little time to get used to.
Part 2: Part 2 was the hardest part of the assignment. It required to get two digital inputs and outputs. This required some Arduino code and connecting the breadboard and Arduino. The hardest part is having a fear of breaking the Arduino. I had a hard time getting the Neopixel connected to the Arduino as well; could not understand what was wrong with the code. I was pretty sure that the set up was right, and the code made sense, but there was an error that kept popping up.

In the end, I couldn’t get the thing to work. Getting the Neopixel to work was harder than I expected.
