Trafic Counter
This project is make to keep safety distance
I learn everything from :https://www.instructables.com/Easiest-Traffic-Counter-Using-Arduino/
Prepare All the Materials
1.Arduino
2.Power Cord (for Arduino)
3.Breadboard Ultrasonic sensor
4.Male to Male wires (4)
Try to build them together
This Is the Code
//source example: mechatronics
// defines pins numbers const int trigPin = 9; const int echoPin = 10;
// defines variables
long duration;
int distance;
float counter = 0;
void setup() { pinMode(trigPin, OUTPUT);// Sets the trigPin as an Output
pinMode(echoPin, INPUT);// Sets the echoPin as an Input
Serial.begin(9600);// Starts the serial communication }
void loop() { // Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(3);//改
// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);
// Calculating the distance
distance= duration*0.034/2;
// Prints the distance on the Serial Monitor
Serial.print("Distance: ");
Serial.println(distance);
delay(1000);//改
if (distance < 200 && distance > 10){
counter = counter + 1;
Serial.print("Cars: ");
Serial.println(counter);
delay(1000);//改
}
