int count= 0;

/* The setup() function is called when a sketch starts. It is used to initialize variables, pin modes, start using libraries, etc. This function will only run once, after each power up or reset of the Arduino board. */

void setup()

{

// initialize serial communication at 9600 bits per second:

Serial.begin(9600);

pinMode(13,OUTPUT);

pinMode(12,OUTPUT);

}

/* The loop() function executes the program repeatedly until Specified. */

void loop()

{

// read the input on analog pin 0:

int sensorValue = analogRead(A0);

// print out the value you read:

//Serial.println(sensorValue);

// delay in between reads for stability

if(sensorValue<= 15)

{

digitalWrite(13,HIGH);

digitalWrite(12,LOW);

// Serial.println(count++);

Serial.println(“This is the southern part of magnet”);

Serial.print(“hall Value=”);

Serial.println(sensorValue);

}

else if(sensorValue>=400)

{

digitalWrite(13,LOW);

digitalWrite(12,HIGH);

WORKING

Welcome to the Arduino-Based Project which consists of a Hall Magnetic Sensor. Magnetic sensors are solid-state devices that can be used in many different types of applications such as sensing position, velocity or directional movement. Hall Effect Sensors are devices which are activated by an external magnetic field. The magnetic field has two important characteristics flux density, (B) and polarity (North and South Poles). The output signal from a Hall Effect sensor is the function of magnetic field density around the device. When the magnetic flux density around the sensor exceeds a certain pre-set threshold, the sensor detects it and generates an output voltage called the Hall Voltage, V_H. Here, we will see the Northern and Southern poles of the Magnet as we place it on either side towards the Sensor.
