This is electronics, words such as a FET LIKE this one do not cut it. We need to know exactly what FET you are using, is it that one?
Well Grumpy Mike there's actually a link to the product page for the MOSFET I am using in my last post but I'll post it again:
I'm new to this so I'm not very astute in the language but according to the data sheet I am using a 30A, 60V, ESD Rated, 0.047 Ohm, Logic Level N-Channel Power MOSFET.
Part Number: RFP30N06LE
Brand: P30N06LE
I hope that is sufficient information to identify the part I'm using...
The same goes for the schematic we need to know exactly what you have wired up not what it is similar to.
Again, I am new to this so using CAD programs to create schematics is something I am still learning. The last schematic I posted (Courtesy of Nick Gammon) is the most recent iteration of an ongoing designing process so I am attempting to revise that schematic and its corresponding sketch to achieve the same effect without the shift registers. Not posting it would've given less information to understand what I am describing which, I'm assuming, would make you even more grumpy, Mike.

As for my question, I am specifically asking for assistance in writing a script that receives analog input and maps that data to a PWM pin which will drive the aforementioned MOSFET to control the brightness of a series of LED lights. I have shown EXAMPLES of what I am talking about to give you a better understanding of what I am trying to achieve because no example is EXACTLY what I am trying to accomplish so I must work to incorporate details of each example.
Thanks for any input!
