Arduino-based distance measuring device has versatile applications, contributing to enhanced automation, safety, and efficiency in various domains. Its adaptability and precision make it a valuable tool for a wide range of projects and industries.
Material Required:
1. Bread Board
2. Arduino UNO
3. Display
4. Ultrasonic Sensor
5. potentiometer
6. 9V Battery
7. Few Jumper Wires
Source Code:
/ defines pins numbers
const int trigPin = 9;
const int echoPin = 10;
// defines variables
long duration;
int distance;
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(2);
// 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);
}
