CODING :
int sensorPin=A0;
int sensorValue=0; int piezoPin=9;
void setup(){ pinMode(sensorPin,INPUT);
pinMode(7,OUTPUT);
pinMode(6,OUTPUT);
pinMode(piezoPin,OUTPUT);
digitalWrite(7,HIGH); digitalWrite(6,LOW); }
void loop(){
sensorValue=analogRead(sensorPin);
if(sensorValue<=1000) {digitalWrite(piezoPin,HIGH);
{tone(9,3047,400); noTone(8); }
digitalWrite(7,HIGH); } else
{digitalWrite(piezoPin,LOW); digitalWrite(7,LOW); } sensorValue=1000; }
