Hi everyone, i'm pretty sure i miss something with my MOSFET...
I use a FQP30N06L to control a simple servo motor (4.8-6V).
I use an arduino pro mini 5V. (My servo works without the MOSFET, I tried)
When I plug :
-the DRAIN to the pin (-) of the Servo (to close my circuit),
-the GAIN to pin 9 (and 10k resistor to GND),
-the SOURCE to GND
it doesn't work if I turn ON the pin 9...
Hi,
It sounds like you are switching the power on and off between gnd and the servo gnd, this is not wise as there will be a current path between the arduino control pin and 5V through the servo.
It is best to remove power from the 5V side using a P-CH MOSFET.
Is there a specific reason you need to remove power from the servo?
