PWM i just cant understand

On the Cerbuino be a LED is on pin 13 to ground
I have this code here:

  public partial class Program
    {  
        static PWM MyFader = new PWM(Cpu.PWMChannel.PWM_0, 10000, 0.1, false);
        void ProgramStarted()
        {            
            Debug.Print("Program Started");
            new Thread(ledblink).Start();
        }

        void ledblink()
        {            
            double i = 0.0;
            while (true)            
            {
                MyFader.DutyCycle = i;
                MyFader.Start();
                if ((i += 0.1) >= 1.0)//increases variable "i" i think
                {
                    i = 0.0;
                }
                Thread.Sleep(10);
            }       
        }
    }

Straight from the pwm documentation basically and ive cycled through every PWM on the Cerbuino bee and I just cant figure this pwm out. I don’t have it hooked up to an external jack and im just trying to power an led right now sothat I can move up to powering a servo and turning it

I had a button plugged in when I did pwm10 and It flashed, im so glad. still not the one I want though. Still cycling the new found “after 7”

DONE. FINALLY. IT BLINKS :dance:
:dance:

The very last pin that I tried. I could make a movie off the tension
