I was wondering how I could control the speed of two fans at once from a single output pin (if possible). I have two fans in series that are powered by an external 7.2V battery. I am using an arduino Uno. Is it possible to connect the lead + wire to the input pin somehow (after mosfet regulation) and control both with one analogWrite() command? Thank You.
Is the issue that you are out of pins on your arduino?
Are you trying to control the speed of the two individually?
Is it possible to connect the lead + wire to the input pin somehow
Am I correct in assuming you mean:
Arduino PWM Output > Mosfet > Fans
I am not out of pins and I am trying to control them together as if they were the same fan. And yes, that is the schematic I had in mind.
