Wawa:
It should work ok if your strip isn't that long.
I will be using ~1A/transistor
Wawa:
Mosfets gates can easilly be damaged by ESD. You must have damaged it by handling it wrong.
probably
Wawa:
General rule (on e.g. a breadboard) is to connect the gate last, and disconnect it first.
Tip: When soldering, you short all pins together by running a bare wire through the legs (touching the gate last), then solder, and then remove the wire.
I didnt know that, thanks.
Grumpy_Mike:
resistor not a transistor
Not my native language, I keep messing that up.
Grumpy_Mike:
Now you have a transistor and not a FET then you need that 220R resistor more than ever as without it the Arduino is damaged by having about twice the maximum current taken from it.
I calculated that I need a 330ohm resistor. Shouldnt make much of a difference.
Thank you for your answers.
