With an ATmega328P microcontroller and a MSGEQ7 IC, I was able to control an RGB LED strip based on the frequencies of an audio signal. The PCB layout was designed by myself using EagleCAD, and manufactured using OSH Park's services. The circuit is powered by a DC barrel jack, and takes a signal through a standard audio cable.

From February 2016 - June 2016, I worked as the electrical engineer in a team of four people to design an automated car sunshade. By June, we were able to construct our first prototype using an Arduino as our microcontroller, and 3D-printed parts for the mechanical design. We demoed our prototype at UC San Diego's Triton Entrepreneur Night, 5/24. Our company name was Shaze, and we were a part of UC San Diego's Basement program, an incubator for start-ups.
