help connecting Arduino UNO to n-ch MOSFET via Optocoupler

Grumpy_Mike:

I did not know what exactly grumpy_mike meant with collector, so I looked on Wiki and saw that its the drain.

Wehe I said the collector I meant the collector. There is only one component with a collector and that is the output of the opto isolator.

If you are determine to miss represent what I said I am out of here.

Sorry Sir, I meant no disrespect, but you said

Grumpy_Mike:
... and the FET gates should be connected to the collector of the FETs.

and I wasnt sure what the collector was at FETs, so I went on Wiki and saw

All FETs have source, drain, and gate terminals that correspond roughly to the emitter, collector, and base of BJTs.

so I assumed that collector was the drain. Nothing else. Sorry if I said something wrong. Its quite possible that I only understood the sentence wrong.
