3. WHAT IS THE “JEDD” LED?
• Play on words “ZEDD”
• Traditional LED Board modified to incorporate
musical elements

4. - Create an aesthetic
combination of visual
and audio media
- Can be used for dorm
decoration and party
entertainment
PROJECT PURPOSE

5. POSSIBLE MODIFICATIONS
• Scrolling team name
• Music box to play selected ZEDD songs
• Lyrics scrolling in sync with music
• Equalizer

8. COMPLICATIONS WITH PARTS
• Locating specific parts that were needed to
create LED Board
• Calculating needed resistor value according to
chosen LED lights
• Make sure purchase was within our budget
• Arrival of parts within a timely manner

9. BUILDING INSTRUCTIONS
1. Test parts on Breadboard
2. Solder LEDs to prefboard
3. Solder controlling prefboard
4. Wire controlling prefboard and LED board
together
5. Wire controlling prefboard to Arduino board
6. Program Arduino board
7. Upload code

10. REVOLUTIONIZED DESIGN
• Concept of Multiplexing: Splitting information in
to little pieces and sending it one by one
• Creator of the 24x6 modified the board  made
easier to wire

11. WIRING MADE SIMPLE
3 pins Many shift registers 8 outputs each
• Saves pins and keeps it simple  multiplies
number of outputs

12. COMPLICATIONS WITH BUILDING
• Lyrics are not in sync with music
• Programming Arduino board to incorporate said
music
• Burnt out LED’s
• Program Arduino board to incorporate our
desired modifications

13. PROJECT SCHEDULE
