HD44780 LCD Backlight control with PWM

I have to admit I'm not really up on FETs but I think that link I posted is confusing :stuck_out_tongue:

In your case you don't want the 10Kohm resistor - it was only there on the linked one due to how it was wired with the external supply.

So LED- to D, S to Ground and G to D3

I'd personally put the 150ohm resistor between S and Ground but that's just personal preference
