if you use a FET you can put a resistor in series with
the source to
ground,
amd the 5v gate drive coming from the microcontroller will be lessened by
the
resistor voltage drop. we can look at it tomorrow night if you want.

anybody haz a circuit diagram that limits current
through a transistor by
means of adjusting the duty cycle of a microcontrolloer
(arduino/esp8266)?
seems like all the diagrams i can find use a current sense resistor & not
the mcu
