Hello,
I'm having some problem in writing this program. I cant get the motor to stop when the 'lux' value drops. Here is the code:
#include <AccelStepper.h>
#include <MultiStepper.h>
#include <Wire.h>
#include <BH1750.h>
BH1750 lightMeter;
const int laser_on_off = 12; //laser on
const int limit_SW_L = 3;
const int limit_SW_R = 2;
const int pcb_detect_SW = 4;
const int reset_SW = 5;
const int led_yellow = 6;
const int led_green = 7;
const int led_red = 8;
unsigned long time = millis();
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
AccelStepper stepper1(1, 11, 10); // (Type:driver, STEP, DIR)
MultiStepper StepperControl; // Create instance of MultiStepper
long gotoposition[1];
int sliderPos = 0;
byte
currSwitch1,
lastSwitch1;
byte
currSwitch2,
lastSwitch2;
byte
currSwitch3,
lastSwitch3;
unsigned long

timeStart1;
unsigned long

unsigned long
timeStart3;
bool
bCheckingSwitch1;
bool
bCheckingSwitch2;
bool
bCheckingSwitch3;
void setup()
{
pinMode( limit_SW_L, INPUT_PULLUP );
lastSwitch1 = digitalRead( limit_SW_L );
bCheckingSwitch1 = true;
pinMode( limit_SW_R, INPUT_PULLUP );
lastSwitch2 = digitalRead( limit_SW_R );
bCheckingSwitch2 = true;
pinMode( reset_SW, INPUT_PULLUP );
lastSwitch3 = digitalRead( reset_SW );
bCheckingSwitch3 = false;
pinMode( pcb_detect_SW, INPUT_PULLUP );
lastSwitch3 = digitalRead( pcb_detect_SW );
currSwitch3 = true;
pinMode(laser_on_off, OUTPUT);
digitalWrite(laser_on_off, HIGH);
Serial.begin(9600);
Wire.begin();
lightMeter.begin();
Serial.println(F("BH1750 Test"));
pinMode(laser_on_off, OUTPUT); //laser on
digitalWrite(laser_on_off, HIGH);
}
void loop() {
float lux = lightMeter.readLightLevel(true);
Serial.print("Light: ");
Serial.print(lux);
Serial.println(" lx");
delay(1000);
// read the button input pin:
buttonState = digitalRead(pcb_detect_SW);
// compare the buttonState to its previous state
if (buttonState == LOW && lastButtonState == 0) {
// if the state has changed, increment counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button went from off to on:
buttonPushCounter--;
digitalWrite(laser_on_off, LOW);
// Delay a little bit to avoid bouncing
delay(100);
}
if (lux < 5) { //if light sensor value drops
stepper1.stop(); // stop the motor
}
if (buttonPushCounter % 2 == 0){
delay(30);
StepperControl.addStepper(stepper1);
stepper1.setMaxSpeed(30000);
while (digitalRead(limit_SW_R) != 0) {
stepper1.setSpeed(10000);
stepper1.runSpeed();
}
}
delay(50);
StepperControl.addStepper(stepper1);
stepper1.setMaxSpeed(30000);
while (digitalRead(limit_SW_L) != 0) {
stepper1.setSpeed(-10000);
stepper1.runSpeed();
}
}
}
