Explain the code in deep detail how it works and each line.

#define BAUDRATE 9600

#define pot 0

#define LED 0

float vOUT = 0.0;

float vIN = 0.0;

float R2 = 7500.0;

int value = 0;

bool sendSms = true;

void setup() {

// put your setup code here, to run once:

Serial.begin(BAUDRATE);

}

void loop() {

// put your main code here, to run repeatedly:

value = analogRead(voltageSensor);

vOUT = (value * 5.0) / 1024.0;

vIN = vOUT / (R2 / (R1 + R2));

if (vIN >= 5.0 && vIN <= 10) {

Serial.println("You can Turn ON LED");

int potRead = analogRead(pot);

potRead = map(potRead,0, 1024, 0, 255);

analogWrite(LED, potRead);

} else if (sendSms) {

//Write a cod to send SMS

}
