I have a prototype I’m building that runs a bit hot. Embedded in the enclosure is a Micro Maestro Servo Controller. Currently I’m cooling the inside with a 5V fan connected to the Maestro’s 5V and GND lines. But the prototype is not louder than I would like. I’m wondering if I can control the fan speed using PWM on the signal line. Is this possible with a Micro Maestro? If so, how do I do this using the Arduino library?
