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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
