Light Sensor Stepper Motor Arduino

Mechatronics class project

IN1 to Arduino pin 11

IN2 to Arduino pin 10

IN3 to Arduino pin 9

IN 4 to Arduino pin 8

One side of Photo resistor to 5v

Other side of Photo resistor to A0 on Arduino

Resistor from ground ALSO to A0 (I used 1k)

The breadboard helped me jump 5v to photoresistor & stepper driver (Brown wire NOT used)

LED positive to Arduino pin 7

ground on one side of 1k resistor to LED negative (Flat side) on the other

// Arduino stepper motor control code

#include <Stepper.h>

// Include the header file

// change this to the number of steps on your motor

#define STEPS 32

// create an instance of the stepper class using the steps and pins

Stepper stepper(STEPS, 8, 10, 9, 11);

int val = 0;

int LED = 7;

int LDR = A0;

void setup()

{

Serial.begin(9600);

stepper.setSpeed(200);

pinMode(LED, OUTPUT);

pinMode(LDR, INPUT);

}

void loop()

{

int LDRValue = analogRead(LDR);

Serial.print("sensor = ");

if (LDRValue <=100)

{

digitalWrite(LED, HIGH);

val = Serial.parseInt();

stepper.step(512);

Serial.println(val);

//for debugging

}

else

{

digitalWrite(LED, LOW);

}

}
