I finally finished tweaking the microstepping code for the Arduino motor shield I designed. Basically, if you’re using a stepper motor but the motor is kinda cheap and has big steps (like 7.5deg) then the system will vibrate a lot, even with interleaved stepping and the motion will be very choppy. Microstepping reduces this problem a little by PWMing between steps to create smoother motion. This doesn’t mean you’ve suddenly turned a 48-step motor into a DC servo, but it does help!
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.
