How to control motors from Raspberry Pi with Adafruit DC Motor Controller and CircuitPython - hackster.io. SciJoy learned how to control DC motors with a Raspberry Pi Zero W and an Adafruit Feather Motor Controller board using CircuitPython. They learned how to use the TB6612FNG chip to drive the motors. That chip has two full h-bridge circuits to control the direction of the motors. The Feather also has a PCA9685 chip, which is a PWM driver. It communicates with the Raspberry Pi over I2C. The robot uses the Blinka library to translate between Python 3 and the CircuitPython libraries - YouTube.

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.
