I have the following arduino code to program a car to move when it gets signalled by a sound sensor and stops when it reaches a magnet sensor$.$ The car should move foward when signalled by sound sensor then stop when it reaches magnet sensor in front. Then when signalled again by the sound sensor it should move backwards to the magnet sensor that was at its original position. Furthermore, the care is moving foward to one magent sensor then backwards to another $.$ Will the code I have achieve what I need to$?$What am I missing? What should I improve?

Code I have to far:

#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

void setup$()\{$

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

pinMode$($magnetPin$1,$ INPUT$)$;

pinMode$($magnetPin$2,$ INPUT$)$;

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$2))\{//$ Sound detected and not at stopping position

moveForward$()$;

$\}$ else if $($soundVal $>500$ && digitalRead$($magnetPin$2))\{//$ Sound detected and at stopping position

moveBackward$()$;

$\}$ else $\{$

myStepper.stop$()$; $//$ Stop motor if no sound or at initial position

$\}$

$\}$

void moveForward$()\{$

myStepper.step$($stepsPerRevolution$)$; $//$ Move forward one revolution

delay$(2000)$; $//$ Delay for $2$ seconds

$\}$

void moveBackward$()\{$

myStepper.step$(-$stepsPerRevolution$)$; $//$ Move backward one revolution

delay$(2000)$; $//$ Delay for $2$ seconds

$\}$
