Goal is to create an arduino program that turns on a stepper motor with a sound sensor and it rotate continuously until a magnet sensor is activated and it shuts off. Then once the sound sensor is activated again it goes into the reverse direction until it approaches the other magnet.

Why isn't my code working?

Code:

#include

const int soundPin $=2$; $//$ Analog pin for microphone sensor

const int magnetPin$1=3$; $//$ Digital pin for initial position magnet

const int magnetPin$2=4$; $//$ Digital pin for stopping position magnet

const int stepsPerRevolution $=2048$; $//$ Steps per revolution for $28$BYJ$-48$ stepper motor

Stepper myStepper$($stepsPerRevolution$,8,9,10,11)$; $//$ Define stepper motor pins

int speed $=100$; $//$ Stepper motor speed

unsigned long lastStepTime $=0$; $//$ Time of last step

unsigned long debounceDelay $=50$; $//$ Debounce delay in milliseconds

void setup$()\{$

pinMode$($soundPin$,$ INPUT$)$;

pinMode$($magnetPin$1,$ INPUT$\_$PULLUP$)$;

pinMode$($magnetPin$2,$ INPUT$\_$PULLUP$)$;

myStepper.setSpeed$($speed$)$;

$\}$

void loop$()\{$

int soundVal $=$ analogRead$($soundPin$)$; $//$ Read microphone sensor value

$//$ Check for sound and magnet sensor states

if $($soundVal $>500$ && $!$digitalRead$($magnetPin$2)$ && digitalRead$($magnetPin$1))\{$

$//$ Sound detected, not at stopping position, and not at initial position

moveForward$()$;

$\}$ else if $($soundVal $>500$ && $!$digitalRead$($magnetPin$1)$ && digitalRead$($magnetPin$2))\{$

$//$ Sound detected, not at initial position, and at stopping position

moveBackward$()$;

$\}$

$\}$

void moveForward$()\{$

while $($digitalRead$($magnetPin$2))\{//$ Keep moving until stopping position is reached

if $($millis$()-$ lastStepTime $>=$ debounceDelay$)\{$

myStepper.step$(1)$;

lastStepTime $=$ millis$()$;

$\}$

$\}$

$\}$

void moveBackward$()\{$

while $($digitalRead$($magnetPin$1))\{//$ Keep moving until initial position is reached

if $($millis$()-$ lastStepTime $>=$ debounceDelay$)\{$

myStepper.step$(-1)$;

lastStepTime $=$ millis$()$;

$\}$

$\}$
