One Dimensional Display
http://blog.gonyeo.com/category/odd.html
This project aims to create a single row of RGB LEDs that can be individually controlled by a Raspberry Pi. The Pi will be able to display single colors, basic hardcoded animations, dynamic animations (like audio visualization), and animations in reaction to various events (like someone entered a room, or the user reveived a message on Facebook).
The hardware will consist of packages of one TLC5947, eight RGB LEDs, one voltage regulator, and some capacitors and resistors on a PCB. These circuit boards will be daisy chainable, with an end goal of about 30 boards (240 LEDs).
The hardware will be controlled in roughly the following fashion:
HTML/CSS/Javascript ---> C ---> TLC5947 ---> LEDs
Here's an imcomplete parts list:
- Raspberry Pi
- TLC5947 (LED Driver)
- RGB LEDs (8x the # of TLCs)
- One of the PCBs from the eagle board folder for each TLC
- Resistors & capacitors
- LM3940 (Voltage Regulator)
