I am trying to use the PCA9685 to power a regular desktop pc cooler fan, the idea being to later be able to freely adjust the fan speed depending on the pwm set in the pwm driver.(similar to this) On my Raspi I tried to get the maximum output voltage out of the board using the following python script:
import Adafruit_PCA9685 pwm = Adafruit_PCA9685.PCA9685() pwm.set_pwm_freq(40) pwm.set_pwm(7, 0, 4095)
However, this only turns on the led attached to the fan without turning it. Is there a way to amplify it in a way that still accurately represents a multitude of the pwm voltage set in the program?
