Sound Reactive RGB LED Strip

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.

Automated Car Sunshade

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.

Autonomous Line-Following Car

Competition Day

The car

From November 2015 - May 2016, I was a lead designer for an autonomous line-following car. With a team of four other people, we participated in UC San Diego's Grand PrIEEE competition. The car features a TSL-1401 Linescan Camera as our sensor, a half H-bridge to drive our motor, a servo motor for turning, an Arduino as the microcontroller.
