Step 7Fire it up!!!
iImage Information

Put your system into a carved pumpkin. I chose to cave a drum kit into mine, but you can put anything on it. You will have to cut a hole into the back of your pumpkin for the speakers to fit in. Once you do that, you can connect the speakers to your stereo, your arduino to your computer and your computer to your stereo. Then run your code and play some music. It should start flashing in sync with the music. If it does not, you need to check that:
1. Your leds are connected correctly
2. You programmed the arduino correctly
3. You loaded the processing code correctly
If none of these work, please ask in the comments, or on the forum on my website (forum.covins.ca).
Enjoy!!!
