I’m working on a small vaporizer project as the cheap ones I have right now are rather crap.
I have some IRL Z44N FETs which (from what I understand ) should be able to be switched directly from an Arduino (and pulsed to vary the output)
I’ve verified that the circuit and sketch works with an LED and multi meter and I can vary the brightness/voltage with PWM. However I cannot seem to get it to switch from the 5v from the Arduino with any substantial load on it (2.2ohm on 12v). If I apply 12v to the gate it switches the load fine.
Any help would be greatly apriciated
