One small note from me:

Whatever the choice is, mine IRFZ44 and IRFZ46 most of the time, make sure you do not use resistor between PWM pin and the gate (or base) of the power mosfet or transitor.

Directly connect the pin to the gate (or base).

One other thing to do: if using mosfet, like IRFZ44, have a 10K or 15K res from gate to gnd.


Just test this, load it up and post the result!
