Today in lab we finally got the Neopixels so we got right to work soldering them. We accidentally soldered each Neopixel the wrong way so when they were plugged in none of them worked. We thought the Neopixels didn’t work or there was a problem with the Arduino. After some investigation we figured out we had soldered the wrong end and we fixed the problem by resoldering the other end. Next we got to building the circuit for the two potentiometers, button and the Neopixels. We then started experimenting with the code. We had written some basic setup code before we showed up on that day to try and scroll through the potentiometers. After some minor bug fixings we were able to get the code mostly working for scrolling horizontally and vertically with the two potentiometers.

Here are two pictures of the working neopixels and the circuit:
