This is my first project with arduino.
The idea behind is to control more LED strips by the use of a Logic mosfet, 30N06L in my case.
I am running into a small difficulty, at the moment there are 2:
1 - When powering the arduino from a 3s lipo battery the TX and RX LEDs light up and the arduino won`t work properly (this is not a big problem as I might use a converter and simply supply 5V, as it would be much healthier for the nano board)
2 - When connecting the MOSFET, in the off state the LED strip doesn`t switch totally off but dims slightly. I tried 10k resistor between gate and source, the 220ohm resistor between digital output pin and gate, nothing helped. Did I somehow manage to accidentally fry the mosfet?
In the attached schematic assume top rail is +12v, bottom rail +5v.
I have read other topics opened on the same problem, but their solutions, unfortunately, did not help me
