First, I'm am new to using transistors and MOSFETs in electronics circuits.
I have extremely basic notions of electronics, and am able to setup and use "of the shelf" boards and Arduino modules, and I do know how basic electronic components work.
Now I'm trying to do the jump to start creating a bit more advanced projects, and I'm struggling to do a simple project with recycled components from some PCBs that I recycled with the help of a heat gun.
I have some PWM fans that I can control using the Arduino, but I would like to shut them down completely, which does not happen without a "switch".
Since I don't have a relay at hand, but I have some NPN and PNP transistors, photocouplers and MOSFETs, I wanted to try to do something with them.
I have this compact MIP2M4 MOSFET that supports the load that I'm going to use of 1A, since it's two 12v 0.5A fans.
I don't want the MOSFET to control the speed of the fans, I just want it to power them off when I send a "0" value PWM signal from the Arduino to the fans, and to turn them on when I send a higher PWM value to the fans.
Can someone help me understand how can I wire the MIP2M4 with the Arduino and the fans to achieve this? I tried it with a NPN C2655, but since it got only a 5v signal on the base, it only outputs 4.83v and the fan runs really slow...
Thank you in advance!
