Adafruit 16 Channel Servo Driver with Raspberry Pi

Servo motors are often driven using the PWM outputs available on most embedded MCUs. But while the Pi does have
native HW support for PWM, there is only one PWM channel available to users at GPIO18. That kind of limits your
options if you need to drive more than one servo or if you also want to dim an LED or do some sort of other PWM
goodness as well. Thankfully ... the PI does have HW I2C available, which we can use to communicate with a PWM
driver like the PCA9685, used on Adafruit's 16-channel 12-bit PWM/Servo Driver!
