I am following the Adafruit page regarding the ServoHat for the Raspberry Pi. I am unclear what module to import to get the PWM class. This is the page about using the PWM class: https://learn.adafruit.com/adafruit-16-channel-pwm-servo-hat-for-raspberry-pi/library-reference
They begin by running
pwm = PWM(0x40). However, they don't specify what to import in order to get the
PWM class. Any help would be appreciated.
