From what i see on different suppliers, this strip of lights require 12V, is there any way i can provide that much voltage from arduino, or anything close to it?
Unfortunately, i have no information on my strip of lights...
Sorry, if this is a poor question, i am only a beginner.
I have a couple 2n2222 transistors and UA741CN Op Amps, would those work?
Probably not.
The 741 is a very old op amp and has no role in controlling an LED strip.
The 2n2222 can only handle 500mA of current or so. What current does you LED strip take?
I have never used and know basically nothing about those transistors, whats the basic difference in the field effect type? i would have to do some research while i'm at it.
From what i understand so far, you tell me to use a FET since it has a huge resistance, allowing for practically any current to go through and not damage the semiconductor?
You want an n-channel logic level FET.
That is one where they specify the on resistance Ron at a gate voltage of 5V or so.
Most FETs need 10V on the gate to fully turn them on.
Do not mix this up with a gate threshold voltage of 5V as this is the point where the FET just starts to switch on.
