Title - Synchronized Music-LED Lighting System (we can change it)

Problem Statement - The Hip Hop Xpress buses have been a symbol of African-American music and history in the Champaign-Urbana area for years. From introducing new emerging DJ music technologies in under-resourced parts of the community to displaying African-American music legends, the bus prototypes remains a fusion of African-American art and technology. The “Double Dutch Boom Bus” is the third iteration of the Hip Hop Xpress, however, this project is headed by individuals that lack expertise in electrical and electronics applications. We will be installing an LED lighting system that is synchronized with the pitch of the music playing. The colors and lighting patterns of the LED system will be automated to provide a beautifully synchronized musical experience.

Solution Overview - The solution will be a LED lighting system that is safe and low-voltage around the exterior and potentially the interior of the bus. A potential Bluetooth mobile application can be used to remotely control the different lighting modes of the bus. The incoming audio signals will be processed by a state variable filter to isolate different frequencies. The isolated frequencies of the audio signals will be used by an ARM microcontroller to control the LEDs to change color and brightness.

Solution Components - ARM microcontroller - The memory will store the LED programs and using the integrated A to D converter we can measure the level of the bass signal and define triggers to change colors of lights.

State Variable Filters - This circuit contains op-amps, resistors, and capacitors. This is used to isolate the audio signals that each string of LEDs will work with.

Android App (maybe) - Ideally we can have app control overpowering the lighting system on/off, and possibly to choose the LED programs to run.

Criterion For Success - The Hip Hop Express will be “lit” (pun intended) by colorful LEDs inside and out, in order to promote a fun, high energy, party atmosphere for the members of the community that gather around the bus. We want some of the LEDs to change color along with the bass of the current song being played.

Hyun Yi, Lauren White, and Andri Teneqexhi earned the Instructor's Award in the Fall of 2013 for their work on the Environmental Sensing for Firefighters.

"Engineering is all about solving real life problems and using the solutions to improve the lives of others. ECE 445 allows you to actually delve deeper into what this really means by providing students the chance to undergo the engineering design process. This requires taking all of the theoretical knowledge, lab experiences, and ultimately, everything that you have ever learned in life, and applying it to your project. Though, there is structure to the course and deadlines in place to measure your team's progress, the actual design, implementation, and success of your project is all determined by you. Unlike any other course that I have taken, I've gained an appreciation for the utilization and benefits of external resources, unforeseen scheduling delays, delegating tasks, and most importantly, teamwork. I consider ECE 445 to be a crash course into real life engineering and a guide to become a successful engineer." -- Lauren White
