I ran it on my Adafruit Itsy Bitsy M4, but it'll work on both the Metro M4 and Feather M4 as well. Note that it's necessary to first activate timer TC0, as by default the Adafruit core code doesn't power up timers: TC0, TC1 or TC2.

By default, the fan is drawing some of the 12v to the mosfet itself and thus, by default, it will spin as the mosfet is at a high state. The only way to stop the fan spinning is to make the mosfet change to a low state. arti bahasa madura siput
