Hall Analog (44E402)

Analog magnetic sensor module and a digital interface, built-in 13 LED build a simple circuit to produce a magnetic flash
Makers.13 comes with digital interfaces of the LED, the analog magnetic sensor connected to the power board analog 5 ARDUINO Interfaces, when analog magnetic sensor to a signal, LED lights,otherwise the lights out.

With reference program:
int sensorPin = A5; // select the input pin
int ledPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor
void setup () {
pinMode (ledPin, OUTPUT);
Serial.begin (9600);
}
void loop () {
sensorValue = analogRead (sensorPin);
digitalWrite (ledPin, HIGH);
delay (sensorValue);
digitalWrite (ledPin, LOW);
delay (sensorValue);
Serial.println (sensorValue, DEC);
}
