Stepping Motor (Stepper Class)
This library enables control of stepping motors connected to the GR-SAKURA board. To use, specify #include <stepper.h>
.
Stepper ()
- Description
- This constructor creates Stepper Class instances.
- Syntax
- Stepper(steps, pin1, pin2)
Stepper(steps, pin1, pin2, pin3, pin4) - Parameters
- steps: The number of steps in one revolution (360 degrees) of the motor. 100 indicates 3.6 degrees per step.(int)
pins 1 - 4: Pins for connection to a motor. - Returns
- None
setSpeed
- Description
- Sets the motor speed in rotations per minute (RPMs).
- Syntax
- setSpeed(long rpms)
- Parameters
- rpms: The speed at which the motor should turn in rotations per minute [rpm].
- Returns
- None
step
- Description
- Turns the motor a specific number of steps.
- Syntax
- step(int steps)
- Parameters
- steps: The number of steps to turn the motor - positive to turn one direction, negative to turn the other.
- Returns
- None
Sample Program
#include <Arduino.h>
#include <Stepper.h>
// change this to the number of steps on your motor
#define STEPS 100
// create an instance of the stepper class, specifying
// the number of steps of the motor and the pins it's
// attached to
Stepper stepper(STEPS, 8, 9, 10, 11);
// the previous reading from the analog input
int previous = 0;
void setup()
{
// set the speed of the motor to 30 RPMs
stepper.setSpeed(30);
}
void loop()
{
// get the sensor value
int val = analogRead(A0);
// move a number of steps equal to the change in the
// sensor reading
stepper.step(val - previous);
// remember the previous value of the sensor
previous = val;
}
