Hello,
I'm trying to dim a led-strip that is running on 24v. When I hook it up to a power-supply it's nicely dimming from 24v to 18v. Turns off at +/- 18v.
Now I' trying to regulate the brightness with an esp32 (arduino like). I have created the following circuit:
But the problem is that when the PWM is 0, the led-strip doesn't turn off completely. It's 'stuck' at 19v.
I'm probably using the wrong FET. Could any of you guide me? I'm kinda hopeless at the moment.
Thanks
