Arduino RGB LED + Winamp

Yesterday I saw this posted by majordecibel on the arduino.cc forum. The main difference between mine and his is that i have no hardware. I'm using the same setup as this post except I created a new mod in the SVIS.dll.

the color is on a fade loop, and the brightness is determined by the music. pretty basic code, basic enough that I was able to build it in a few hours. when the delay is below 50ms the color transitions are rough. Also in my code I have it mapped to a min value of  80. this is so that when I have the Arduino unit behind my monitor it doesn't bug the hell out of me.

int blue = 3;
int green = 5;
int red = 6;
int pwr = 11;
long timer;
const long muxInterval = 20;
int mux = 0;
int color[3] = {0,255,255};
int data[10]; 
float percent;
void setup()
{
   Serial.begin(57600);
  pinMode(blue, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(red, OUTPUT);
  pinMode(pwr, OUTPUT);
  timer = millis();
}


void loop(){

 if (Serial.available() > 10) {
 byte i = Serial.read();

 if (int(i) == 255) {
 for (int c = 0; c <= 9; c++){
 data[c] = int(Serial.read());
}
 }
int total = ((data[2] + data[3]) / 2);
total = map(total,0,255,80,255);
//total = 200;
percent = total / 255.00;

   int redTotal =  ((color[2]*percent));
   int greenTotal = ((color[1]*percent));
   int blueTotal = ((color[0]*percent));


  analogWrite(pwr, total);
  analogWrite(red, color[2]);
  analogWrite(green, color[1]);
  analogWrite(blue, color[0]);

if (millis() - timer > muxInterval) { 
   timer = millis(); mux++; 
   if (mux > 1530){
     mux = 1;
   }
   if (mux >= 1 && mux <= 255) {
     color[2] -= 1;
   }
   if (mux >= 256 && mux <= 510) {
      color[0] += 1;
   }
   if (mux >= 511 && mux <= 765) {
     color[1] -= 1;
   }
   if (mux >= 766 && mux <= 1020) {
     color[2] += 1;
   }
   if (mux >= 1021 && mux <= 1275) {
     color[0] -= 1;
   }
   if (mux >= 1276 && mux <= 1530) {
     color[1] += 1;
   }
}
 }

New AlpineCave.com logo

I still don't know what I'm doing with AlpineCave.com, It was too good of a domain name to pass up so I just had to get it.  however I was never really happy with the current logo.  It was clever, but the "A" didn't translate too well. It read more like alpinecave without the "A".

Arduino + Winamp vu meter

This is one of the pieces of code that I've delayed posting for a long time. For those that wanted it I'm deeply sorry that it has taken me this long.

This is a Script that really only works is you have all the pieces.

So first you need the plugin for winamp that Maceger provided to me.

http://www.macetech.com/wa502_sdk.zip

also my version is available on my download page

** for this to work you need to download and open the project in visual studio and do a search for "COM" and change it to your COM port of your computer. Then compile the dll, and put it into the  C:\Program Files\Winamp\Plugins folder ***

second you need softPWM (optional)

http://arduino.cc/forum/index.php/topic,19451.0.html

if you chose not to use it you will need to change SoftPWMSet to digitalWrite, and remove all SoftPWM code.

support topics on my project can be found at the fallowing links.

Zen Trail with Bogley.com

Well back again today with the Bogley gang today we hit up Zen Trail and Bearclaw right after. we spent most of the day playing on the rocks, and a few of them with the DH bikes were praying for the climbing to end and the down hill to start.  what usually happens is when you first ride this trail you hate it, but when your crazy enough to come back for seconds is when you realize it's really not that bad of a trail.  Justin McFarland  got some  great videos and pictures, so enjoy.

JEM Trail with Bogley.com

I meet up with a few friends from bogley today and rode the JEM Trail. not much has changed since the last visit. the corners have hardened up quite a bit and was easy to keep traction. we stopped in a few parts to do some drops.. I chose not to do it because i have a hardtail with 3 inches of travel in the front, now if i was ridding a full DH bike like they were I probably would have given it a go.
