So after trying out pretty much every option imaginable I decided to ignore the tutorial completely and work my way from the ground up in order to try and identify the problem.

I am using the simplest possible test setup:

I simplified (in my view) the Arduino code to the following:

Code:

int red, green, blue;
int redPin =9;
int greenPin =10;
int bluePin =11;

void setup()
{
  Serial.begin(38400);
  int red=255;
  int blue=255;
  int green=255;
}

void loop()
{
if (Serial.available()>=4) {
if(Serial.read() == 0xaa){
red = Serial.read();
green= Serial.read();
blue = Serial.read();
}
}

analogWrite (redPin, red);
analogWrite (greenPin, green);
analogWrite (bluePin, blue);
delay(10); //just to be safe
}

and my boblight.conf now looks like this:

Code:

[global]
interface       127.0.0.1
port            19333

[device]

#arduino bootloader runs when opening the serial port for the first time
#delay transmission one second after opening so we don.t send shit to the bootloader

The end result is that boblight is now showing some signs of life and seems to be actually working. My only problem is that the red LED does not light up at all for some reason. It's not a hardware issue as I tested it with a direct +5V and it lit up fine. Any ideas what it might be?

Does the red LED work on the other channels? Tried a smaller resistor?
I wouldn´t change the arduino code because a) the one from bobo1on1 is proven and b)you probably won´t get support from the devs when using some modified software code
