It looks like you are trying to add another LED/Mosfet? I have done it this way, I have 3 on mine:
To do this I may or may not have used some examples I found on this forum. I basically add the pins I am using (PWM capable) into an array. I have 4 pins defined (3 is in there twice) to get around the array references starting from 0. Probably a better way to do that but this was my quick way round it.
I have basically adapted the code from the example LED Dimmer sketch to work with the array / multiple child devices.
Hopefully thats helpful and what you were after?
