Adafruit 16 Channel Servo Driver with Raspberry Pi From the Learning System #piday #raspberrypi @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!
Using this breakout, you can easily drive up to 16 servo motors on your Raspberry Pi using our painless Python library and this tutorial.
Note this cannot be used for driving anything other than analog (1-2 millisecond pulse drive) servos. DC motors, AC motors and digital servos are not going to work.
Adafruit 16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685 – You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout. (read more)
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
