Wawa:
Use a 220ohm resistor between pin and gate, and a 10k resistor from pin to ground.Did you set the (PWM?) pin to OUTPUT with pinMode().
Did you connect source to supply(-) and Arduino ground.
Did you use a breadboard, and can it handle the (unknown) strip current.
Does the breadboard have uninterrupted power rails.Post your code,a and a clear picture of the wiring.
Read the forum rules first.

I have honestly no Idea why I am using 1k resistors. I started this project last year and just came back to it. I updated the question. Am going to swap the resistors the way you told me to. If this doesnt fix it, I will provide wiring. Thanks for now man
