  • Drive a Stepper Motor with an Arduino and a A4988 Stepstick/Pololu driver

    PS would it not make sense to have your primary image showing what you are using rather than an apparently random pick of one of the many combos of motor/driver you aren't using?

    Thanks for a concise summary. You didn't mention that it is entirely possible to run motors at much higher voltage/ current combos it it's not continuous, eg if you switch off between steps using the enable pin (which you accidently left off your fritzing diagram - you mentioned connecting pin 6 in the text).Also the higher the voltage the faster/ more accurate the step and generally I found it a good idea to use the highest possible voltage and correspondingly decrease the current to avoid burning out the motor. Thus it should have been entirely possible to use your adafruit driver with your stated specs.Finally I've never calculated current and measured voltage at the stepstick, always just turned the pot down low then manually adjusted the current up to get reliable function.Also mic...see more »Thanks for a concise summary.
