It makes wiring much easier and is a great option if you need a more permanent solution than a breadboard. Such a shield already includes capacitors and offers an easy way to select the microstepping resolution.
I like to use this driver in combination with a CNC-shield or expansion board. I also have an article on How To Drive a Stepper Motor using the A4988 driver and ESP32 if you want to work with an ESP32 microcontroller instead. TB6600 Stepper Motor Driver with Arduino Tutorial.
How to control a Stepper Motor with Arduino Motor Shield Rev3.28BYJ-48 Stepper Motor with ULN2003 Driver and Arduino Tutorial.How to control a stepper motor with DRV8825 driver and Arduino.If you would like to learn more about other stepper motor drivers, then the articles below might be useful: This library is fairly easy to use and can greatly improve the performance of your hardware.Īfter each example, I break down and explain how the code works, so you should have no problems modifying it to suit your needs. I have included a wiring diagram, a tutorial on how to set the current limit and many example codes.Īlthough you can use this driver without an Arduino library, I highly recommend you also take a look at the example code for the AccelStepper library at the end of this tutorial. See FAQ:Where can I find “specific part” for information about looking for existing part files, and information needed to create new parts.This article includes everything you need to know about controlling a stepper motor with the A4988 stepper motor driver and Arduino. Either as is, or as a base for something else. I would not try to use that downloaded part with out some serious cleanup first. To figure out where things are supposed to be, and what should be connected together. To do this properly, a datasheet for the part is really needed. What I see does not have labels except on breadboard, and the part validation tool I use has many complaints. Jumper wires (or cable) would run from the board to a header on the pcb instead. Really, this board does not normally need a pcb view. Spacing and position of the pins on the pcb view also look off. I do not see any of that in the part definition though. Like multiple gnd, or +5V connecting to other +5. Wires are not connecting where they are dragged to except in breadboard view.įewer pins in schematic “CAN” be normal, in cases where multiple physical pins are connected together inside the part. My initial testing of a fresh download of that part says it is broken.
