But no result. is the low and high end of the original data set. This driver can be used with the same code as the A4988 … * by Dejan Nedelkovski, www.HowToMechatronics.com * https://howtomechatronics.com/tutorials/arduino/how-to-control-stepper-motor-with-a4988-driver-and-arduino///Enables the motor to move in a particular direction// Gets custom delay values from the custom speedUp function// Makes pules with custom delay, depending on the Potentiometer, from which the speed of the motor depends// Converts the read values of the potentiometer from 0 to 1023 into desired delay values (300 to 4000) This program drives a unipolar or bipolar stepper motor.

const byte X_EN = 6;), so that you can easily redefine them and avoid forgetting one. And so it behaves:To ensure a drop in performance is still a 47 nF Capacitator when supplying the 12 volts necessary.If you do not have any potentiometers at your disposal, you can also use software-based potentiometers: for this purpose, we integrate the library from Blynk. The thought is that first stepper motor will carry out a first horizontal scan and then as it reaches to its initial position, second stepper motor will move a single step in vertical direction.

This loop continues for 20 steps of Y motor. It is a basic level code and I would really appreciate the help for helping me out. Then Y motor will movie one step up.
Because when they are used together, A4988 connected motor is not working and HR4988 connected motor is working. At the end of 20th, Y motor moves 20 steps down. With one motor working and one not it implies to me that either the motor is broken, the wiring is broken or the driver circuit is broken. Go Down. These projects are designed for younger kids who want to get introduced IoT.A simple way to control a motor with a potentiometer and an Arduino.I was struggling with the wiring of a stepper motor and so I hope I can take the fear out of you with this article: I use the same PINs to illustrate two different devices driving the I found in my component box an alternative Stepper Motor Driver, which I can also recommend: the Update 04.10.2018 - Control the speed with potentiometer Now when I had the structure in front of me, it was now to influence the rotational speed to take: it offers a potentiometer. Maybe the stepper is a 200 step/turn, and in one turn you move 1mm, so the full 20 steps are 0.1mm and you can't see it... Can you try swapping X and Y motors? Only integer values are supported in C. I have checked my circuit, motors and drivers and everything is working fine.

Here's an introduction to control a Nema 17 stepper motor with the help of the Adafruit TB6612 OR A4988 Stepstick OR PHPoC PES-2405 R2Here's an introduction to control a Nema 17 stepper motor with the help of the Adafruit TB6612 OR A4988 Stepstick OR PHPoC PES-2405 R2In the beginning, a short test with an LED is worthwhile to find out the correct cable routing of the two coils in the stepper: pick up an LED and insert the two feet into the adapter: move the motor with your hand.If the LED is lit you have identified the two cable for connection to the MOTORA or MOTORB breakout board.The same structure works with the given library "Stepper" examples for both the Uno and the Photon (here only the PINs in the original example have to be replaced by 4, 5, 6 and 7). are the low and high values of the mapped data set.
int PotiValue = param.asInt(); // assigning incoming value from pin V0 to a variable @ code gorilla - No both motors will not run at the same time.

I am trying to run two stepper motors NEMA 17 through respective A4988 driver and controlling via Arduino Uno.. @ frarugi - Yes, second motor is not at all working.
