Sound controlled LED Structure
Feb 2018 - Mar 2018
SUTD IEEE Student Chapter
Singapore University of Technology and Design OpenHouse
The aim for this project is to design an LED structure for SUTD IEEE Student Chapter that can be used in SUTD open house to promote both SUTD and IEEE name to the public.
​
First of all, we did up the CAD for the entire structure and proceed to laser cut the structures out using lasercutter and wood.
​
​
After which, we attached strips of WS2812 LED strip into the structure. All the structure are then attached to a Rasbperry Pi
3 which controls the color of the light and the intensity of the light.
​
Finally, we made a script that controls the color and brightness according to the surrounding music/sound that is played.
To the right is the working prototype that changes the color of the LED structure according to the base of the music. (On your audio!)
​
In the project, my role was programming the Raspberry Pi with the color control script along with Abhimanyu. A USB microphone is connected to the Raspberry Pi to obtain sound wave input which is pumped into the script and subsequently control the LED.
The LED structure was ultimately displayed in SUTD Openhouse 2018, 5th Row showcase and EPD Nightwalk room.
​
Huge thanks to the people who made it possible: Edmund, Kevin, Abhimanyu, Tan You and Zhi Xin!
