Stepper Motor Control (步進馬達控制) = Motoduino (Arduino+293D) + Stepper Motor

Motoduino這塊板子也可以控制步進馬達(stepper motor), 方法很簡單, 手上這顆是二相激磁四線式步進馬達, 電壓 5V, 精度1.8度, 電流 0.3A, 四線接法: 紅線接M1+, 棕色接M1-, 藍色接 M2-, 黃色接 M2+. 影片中實驗是順時針走 200步(200x1.8度=360)剛好一圈,逆時針走200步回原點.

使用材料:


1. Motoduino
2. Stepper Motor (KH42JM2B011) 5V, 0.3A, 1.8 Deg.

The Sketch(for Motoduino):


#include <Stepper.h>

const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution
                                     // for your motor
const int Motor_E1 = 5; // digital pin 5 of Arduino (PWM)  
const int Motor_E2 = 6;  // digital pin 6 of Arduino (PWM)
const int Motor_M1 = 7;     // digital pin 7 of Arduino
const int Motor_M2 = 8;    // digital pin 8 of Arduino
//Stepper myStepper(stepsPerRevolution, 8,9,10,11);          
Stepper myStepper(stepsPerRevolution, Motor_M1, Motor_M2);          

void setup() {
  // set the speed at 60 rpm:
  myStepper.setSpeed(60);
  // initialize the serial port:
  Serial.begin(9600);
  pinMode(Motor_M1, OUTPUT);
  pinMode(Motor_M2, OUTPUT);

  digitalWrite( Motor_E1, HIGH);  // speed control
  digitalWrite( Motor_E2, HIGH);  // speed control
}

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

   // step one revolution in the other direction:
  Serial.println("counterclockwise");
  myStepper.step(-stepsPerRevolution);
  delay(500);
}
