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);
}
}
