How do I use ultrasonic sensors with Arduino?

How do I use ultrasonic sensors with Arduino?

To use ultrasonic sensors with Arduino, you'll need to connect the sensor's VCC, GND, Trigger, and Echo pins to the Arduino.

What code do I need to upload to the Arduino?

You can use the following code snippet:

#include <NewPing.h>
#define TRIGGER_PIN  12
#define ECHO_PIN     11
#define MAX_DISTANCE 200

NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE);

void setup() {
  Serial.begin(9600);
}

void loop() {
  delay(50);
  Serial.print("Distance: ");
  Serial.print(sonar.ping_cm());
  Serial.println("cm");
}

How do I power the ultrasonic sensor?

You can power the ultrasonic sensor by connecting its VCC pin to the 5V pin on the Arduino and the GND pin to the ground.

Can I use multiple ultrasonic sensors?

Yes, you can use multiple ultrasonic sensors by connecting them to different trigger and echo pins and modifying the code accordingly.
