Topic: Flashing LED's to music (Read 2450 times) previous topic - next topic

First off thank you to anyone who is taking the time to read hoping to be able to help.  I have only posted one other time in the forum and it was a major success, so I will try again. 

Here is the setup:

I am running and Arduino Uno with an Adafruit MP3 shield.  I am currently controlling two Max7219 LED controllers and an RGB led strip.  I have five buttons hooked to the Analog in pins. 


What I want to accomplish:

I would like to be able to play a file from the MP3 shield and have the LED's blink to the music.  I don't want to write hundreds of lines of code to make it look like they are flashing to the music.  I would like to have the Matrices as well as the strip flash but would be okay with just one of them flashing.

Is this even a possibility with what I am running?  Any help would be greatly appreciated?

Does the reset pin on that shield need to be connected to a PWM pin?  The schematic provided has it connected to digital 5.  I currently only have digital 12, 13, 0, 1 and Analog  A5 that are not being utilized.  As well as the ICSP pins.

think for a reset PWM is not needed so you should be able to use another pin as reset pin.

The article at tronixstuff on using the MSGEQ7 as a spectrum analyser is great. I adapted the codes there to build my project using LED Matrix instead of LCD display. You may see my project at http://www.instructables.com/id/Arduino-based-Bi-color-LED-Matrix-Audio-Spectrum-V/

I am looking at buying a few of those just to play with !! :)
