Hi, I need some help figuring out how to have the sound stop after the distance is no longer greater than 300. Right now once it gets to
while(x>300)
{
tone(8,500);
}
noTone(8);
Heres the full code:
int x;
//const int switchPin = 2;
const int motorPin = 9;
//int switchState =0;
void setup()
{
Serial.begin(9600);
pinMode(9,OUTPUT);
delay(5000);
run();
delay(5000);
check();
}
void loop()
{
}
void run(){
digitalWrite(9,HIGH);
tone(8,500);
delay(400);
digitalWrite(9,LOW);
noTone(8);}
void check(){
x= analogRead(2);
while(x>300)
{
tone(8,500);
}
noTone(8);
}
