MicroPython Hardware: PCA9685 PWM & Servo Driver is a new guide in the learning system:
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.
