如何仅使用一个Arduino Uno使两个步进电机在相同的时间和相同的方向旋转？

Question

My current code:

    #include <Stepper.h>

    const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution


    Stepper myStepper(stepsPerRevolution, 3, 4, 5, 6);
    Stepper secondStepper(stepsPerRevolution, 8, 9, 10, 11);

    void setup() {
    // set the speed at 60 rpm:
    myStepper.setSpeed(60);
    // initialize the serial port:
    Serial.begin(9600);

    secondStepper.setSpeed(60);
    // initialize the serial port:
    Serial.begin(9600);
    }

    void loop() {
    // step one revolution  in one direction:
    Serial.println("clockwise");
    myStepper.step(stepsPerRevolution);
    Serial.println("clockwise");
    secondStepper.step(stepsPerRevolution);
    delay(500);
    }

I was working on a project involving the above code during a hackathon this past weekend, but I couldn't get the two motors to move simultaneously. I was wondering if anyone on here knew how to do it properly so that I may be better prepared in the future.

I'm using the Arduino IDE, if that matters.

Answer 1

You need a non-blocking step (or start) call that starts the motion and returns immediately. After starting the two motions, you would then wait for an asynchronous callback from each motor indicating that the motion has completed. One thread per motor would work in a straightforward manner. The main thread would wait for both motor threads to complete before proceeding.

Answer 2

是的，您可以并联两个电动机，以在Ramps 1.4板上控制z轴！
