Im using stepper motors in a rat sculpture. Im trining the rats to use the feeding systems and activate the doors.
Only thing I need help with the code for the stepper motor as I am a newb and totally useless atm.
The 5v stepper motor is wired to a L293d and that is wired upto my D arduino
The rats will press the button activating the stepper motor which will turn xx amount of steps then it will pause for X seconds and reverse x steps to original
This is what I was doing last
#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(0);
// 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;
}
So you want to take out the analogRead() and use a button instead? You just need to de-bounce the button
void loop() {
static unsigned long lastButtonTime = 0;
static boolean lastButtonState = false;
boolean newButtonState = digitaRead(buttonPin);
unsigned long currentTime = millis();
// Make sure it has been at least 100 milliseconds since the last button change to filter out bounces
if (newButtonState != lastButtonState && currentTime-lastButtonTime > 100) [
lastButtonTime = currentTime;
lastButtonState = newButtonState;
if (newButtonState) { // Fresh button press
stepper.step(XX);
delay(X*1000); // Wait X seconds
stepper.step(-XX);
}
}
}
This is what I have right now, it tells me that Digital read was not declared in this scope?? Thanks a mill for the reply
#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;
const int buttonPin = 2; // the number of the pushbutton pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup()
{
// set the speed of the motor to 30 RPMs
stepper.setSpeed(30);
}
boolean newButtonState = digitaRead(buttonPin);
unsigned long currentTime = millis();
// Make sure it has been at least 100 milliseconds since the last button change to filter out bounces
if (newButtonState != lastButtonState && currentTime-lastButtonTime > 100) [
lastButtonTime = currentTime;
lastButtonState = newButtonState;
if (newButtonState) { // Fresh button press
stepper.step(XX);
delay(X*1000); // Wait X seconds
stepper.step(-XX);
}
}
}
}
