GMU:Connecting Max to the World/Gracia Quintero

IDEA

My idea is to control a small set of LED lights alongside with the music I program using MSP in order to create a visual sequence. I plan on building a small structure which is illuminated with a LED light strip smoothly alongside with the rhythm of the music, like you can see in the following videos:

Color LED light bulb In this reference, the developer used a microphone in order to alternate the change of colors according to the information received by the microphone.

This is a much more simpler example of installation with only three LED lights, in the original video, the lights dance to the music. Bottle LED light

FIRST ATTEMPT

In the first attempt, I tried using the 16 channel Relay Module and using the Christmas light tutorial. I was able to upload a code to it, but it wasn't being transmitted to the LED light installation.

It was a little frustrating, as it was the winter break and couldn't really move forward with this technique. I kept looking online for an easier way for me to be able to communicate Max and Arduino with the LED lights.

A little while later, I found a very helpful tutorial, which allowed me to communicate arduino with my set of LEDs. [1]. I followed this tutorial and to my surprise, it really worked.

  This is the arduino connection I used as instructed by the tutotial

  And this is my connection:

And here you can find the video of when it first worked.

CONNECTING THE CODE TO MAX

In this point, I talked to my teacher Miga, and he gave me a little clue to try to use the old patch I had used in a previous exercise and try to connect it to the new code I had in the arduino software. I tried several ways, until I realized that the easiest way was exactly modifying the code I had already programed a while before.

So, here you have it: Max code, arduino code, and a video of the LED lights synchronized to any audio source the Computer's microphone detects.

Arduino code: File:sketch_mar12a.ino MAx code: File:FINAL PATCH.maxpat
