There are lots of stepper motor control library but in this tutorial, we will use arduino stepper motor code without library.

In this simple Arduino stepper motor tutorial, we will rotate the Nema17 motor one full cycle in clockwise direction and after 1.5 second later rotate the motor one full cycle in anti-clockwise cycle.

The following picture shows how to connect Arduino to A4988. The last other two pins, the VDD(pin 9) and Ground pins(pin 10) shown in the above schematic, need to be connected to the 5V and GND pin of the Arduino respectively. In this arduino stepper motor tutorial, we will connect STEP pin to digital pin 9 andДIRECTION pin to digital pin 8 of Arduino. These two pins needs to be connected to the Arduino digital pins. If low pulse is sent then the A4988 will rotate the motor in anti-clockwise direction. If we send a high pulse to A4988 Direction pin then A4988 will cause the stepper motor to rotate in clockwise direction. The direction(DIR) pin is used to control the stepper motor direction. A longer step pulse will rotate the motor faster. The STEP signal controls the speed of the stepper motor Nema17. The Arduino uses these pins for stepper motor speed and direction control.Sending a high pulse from Arduino to STEP pin moves the motor one step. Next is the STEP and DIRECTION(DIR) pins of the A4988 driver. In our case we will tie them together.ДЄrduino Stepper Motor Speed and Direction Control

When the reset is made active low then the A4988 driver is set to a predefined Home state until the reset goes high again. This happens because when sleep mode is activated the internal circuitry(output FETs, charge pumps, current regulator) are disabled and thereby power consumption is lowered. The SLEEP pin is used to drive the A4988 into sleeping mode in which case the driver will minimize power consumed by the driver. The ! SLEEP and !RESET pins (! meaning here active low) controls the sleep mode and the reset of the A4988 driver. I did just find this post however that seems like it might actually be a non issue if I provide the stepper with a 5v or 5.5v supply.Here we will use full step mode which means that the MS3, MS2 and MS1 pins of the A4988 driver are left unconnected because internally they are connected to pull-down resistors which keeps them at low level logic.

Perhaps just a diode with the right level of voltage drop in the correct orientations for each phase? I'll need to be able to move the stepper both directions though so I imagine that wouldn't work. I'm not sure if maybe there's just an obscure driver package that outputs a 3.5v signal or something along those lines, but I'm wondering what I need to do to use a 3.3 to 3.5v stepper motor with a 5v driver without burning it out, and likely drawing the full 1.5 or 2 amps that the driver can provide.

So I'm starting to delve into stepper motors with arduino for a project I'm working on, which is proving interesting so far, with me first getting a motor far too small, and then also finding out that using a stepper motor is a blocking function, and not playing well with my code.ДЄnyhow, my concern is that all of the beefy nema 17 stepper motors are rated at 3v to 3.5v, the one I'm looking at rated for 3.35v for driving, however, all of the stepper motor drivers I can find capable of 1.5-2 amp loads have a 5 volt output.
