Pin – = GND, connect to GND
Pin (middle pin) +5 v, connect to +5v
Pin S signal, connect to Arduino pin 3 (or your own choice buit code would need updated)

Code

[codesyntax lang=”cpp”]

int LedPin = 13 ;
int HallPin = 3; 
int val; // define numeric variables val

void setup ()
{
pinMode (LedPin, OUTPUT) ;
pinMode (HallPin, INPUT) ;
}

void loop ()
{
val = digitalRead (HallPin) ; // read digital interface is assigned a value of 3 val
if (val == HIGH) // When the shock sensor detects a signal, LED flashes
{
digitalWrite (LedPin, LOW);
}
else
{
digitalWrite (LedPin, HIGH);
}
}
