const int trig = 6; // Trigger pin
const int echo = 7; // Echo pin

long totaltime;
long distance;

void setup() {
pinMode(trig, OUTPUT); // Set trig pin as output
pinMode(echo, INPUT); // Set echo pin as input
Serial.begin(9600); // Start serial communication at 9600 baud rate
}

void loop() {
// Clear the trig pin by setting it LOW
digitalWrite(trig, LOW);
delayMicroseconds(2);

// Trigger the sensor by setting the trig pin HIGH for 10 microseconds
digitalWrite(trig, HIGH);
delayMicroseconds(10);
digitalWrite(trig, LOW);

// Read the echo pin and calculate the time it takes for the echo to return
totaltime = pulseIn(echo, HIGH);

// Calculate the distance (in cm) based on the speed of sound (343 m/s)
distance = totaltime * 0.034 / 2;

// Print the distance to the Serial Monitor
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");

delay(500); // Wait for half a second before the next reading
}

can you pls making video digital measuring tool with this.
pls be note i am not an electronic student. i am hobbyist.

suggest to do with mini beardboard or without bearboard with wiring picture is easy to understand for me
