Advice on LED

Projects General Guidance

Hello, in this pic attachment I have a N-channel no after hooked up to a potentiometer and I'm controlling a 9-12v led strip only 1 ft long.
I have the gate of the MOSFET hooked up to the middle pin of POT and I have the LED hooked up to the source and ground with a small rating capacitor in parallel with the less and I'm powering with a 9v battery
My circuit some the light very smoothly with no flicker (as opposed to when I just used a pot)
I understand that PWM IS more efficient but I want to control without the use of OWN.
Is there anything wrong with the circuit besides it giving of extra heat?
Any advice
Thanks

That's not a circuit it's a picture of a rat's nest too small to see any detail.

And what do these mean?
"small rating capacitor in parallel with the less"
"some the light very smoothly"

And what does this have to do with Arduinos?

I think you are controlling strip brightness by using a pot on a mosfet gate. This means running the mosfet in the heat-generating middle ground.
I don't think your setup will burn, as you are using presumably a tiny 9V battery. It will work until it doesn't. And its behavior is temperature dependent. I wouldn't change power supplies until you learn a bit more.
And as asked, what Arduino?

Thanks INTP and sorry for the bad writing. I am at work thank you for understanding and not being rude like SlipStick
If there was a way I could add negative karma I would do it to SlipStick who is doing nothing but discouraging pople.
