Guide Update: Raspberry Pi Stepper Motors #adafruit #circuitpython #raspberrypi @adafruit
We’ve updated the guide for that explains how to drive Stepper Motors using a Raspberry Pi. The code now uses the CircuitPython libraries and is Python 3.0 compatible. This tutorial is particularly good for someone getting into driving DC motors as it explains how to use the the L293D and ULN2803 driver chips directly. Most of the motor guides written in CircuitPython tend to abstract the code and pins, but this tutorial gets you down and dirty with direct pin to motor coil stepping action.
This guide update allows for all 20-pin and 40-pin Raspberry Pi’s (every Pi released to date but the compute modules) to run the same example code without modification. Either driver chip the L293D or ULN2803 can be used without code changes (although the wiring is different).
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
