Overview

Servo motors are one way to make projects come to life with exciting movements like steering robots, flipping switches, and more.  To control a servo you need to generate a special PWM, or pulse-width modulation, signal.  Most development boards can generate a few basic PWM signals, but what if you need to control a lot of servos or don't have a board with PWM support?  The PCA9685 PWM driver board comes to the rescue!  This driver board can generate up to 16-channels (or 8-channels in FeatherWing form) of PWM signals--perfect for driving many servos!

This guide explores how to use the PCA9685 PWM & Servo driver with MicroPython.  You'll learn how to connect the PCA9685 to a MicroPython board and use it to control LED brightness and move servos.  

To follow this guide you'll want to be familiar with MicroPython by reading these guides:
