Story

This easy Arduino project makes a parking sensor.

#include <Ultrasonic.h> 
Ultrasonic ultrasonic(6,5); 
// pin 6 trig , pin 5 echo
const int buzzer = 7; 
void setup(){ 
pinMode(buzzer,OUTPUT); // pin buzzer
} 
void loop(){ 
int dist = ultrasonic.Ranging(CM); 
if (dist < 100) { distance
 tone(buzzer,1000); 
    delay(40); 
  noTone(buzzer); 
    delay(dist*4); 
  } 
delay(100);  
}
