I am completely new to working with Arduinos and hope this is possible. I am a digital design student and I am attempting to create a project where a board of LED lights will randomly fade in and out when sound is detected. The idea behind the project is to make an interactive wall that creates an abstract visual of a conversation through the LED lights.
Here is a video I found that does something similar to what I would need:
Like I said, I'm totally new to this and need all the help and guidance I can get. A huge thank you will be involved in my project to any help.
Start with something like this shield https://www.sparkfun.com/products/10306 that has a 7 band graphics equalizer chip. This will split the audio into 7 separate frequencies and tell you the loudness of each frequency. Use these values to drive the brightness of different LED's. The UNO only has 6 PWM output pins so you could ignore one of the frequencies or maybe use SoftPWM http://arduino.cc/forum/index.php/topic,19451.0.html to drive all seven.
That's brilliant, thank you so much. Do you know if there are kits or tutorials for doing this like this? I wouldn't even know where to start. I will look into the equilizer you've mentions now.
The Sparkfun product page has links to the datasheet for the equalizer chip (MSGEQ7) and a sample program to read/display the results on some Bliptronics.com LED modules. You should be able to adapt the program to your own needs.
the tiltle of thr music please?
