The help I've received in the general channel around MOSFETs has given me the confidence to attempt a simple circuit using a 12V 20A power supply to drive a ton of 12V white LEDs, with 5V PWM output from an Ardunio Nano going into a logic-level n-channel MOSFET (P30N06LE).
Unfortunately the story doesn't end there (otherwise I wouldn't be writing this post): I have tried a number of ways to wire this up with very unsatisfactory results.
Here are my most recent attempts. In later attempts I threw in a resistor at random because I've seen them in some examples on the web, though I really don't know what function they would serve.
I actually had the whole thing working on the breadboard at one point (without resistors) - the LEDs were pulsing as intended, but something was lost in translation when I moved it to the soldering stage (and incidentally started powering the Arduino off the same power rail as the LEDs) and now I'm back to square one.
I think the datasheet is this one: https://www.sparkfun.com/datasheets/Components/General/RFP30N06LE.pdf, which is why I've labeled the GDS pins the way I have.
Any help would be appreciated, and explanations doubly so. Thank you in advance for taking the time to answer what I'm sure is a question of the most basic nature.
