How to measure distance with an Arduino and Ultrasonic Sensor // HC-SR04

In this video I will show you a relatively accurate way to measure distance using and Arduino and an HC-SR04 ultrasonic sensor. I will walk you through the theory, setup, and coding using an Arduino.

For people who are lazy
const int triggerPin = 9;
const int echoPin = 10;
float pulse_width, distance;
void setup() {
// put your setup code here, to run once:
pinMode(triggerPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
digitalWrite(triggerPin, LOW);
delayMicroseconds(2);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(triggerPin, HIGH);
delayMicroseconds(10);
digitalWrite(triggerPin, LOW);
pulse_width = pulseIn(echoPin, HIGH);
distance = (pulse_width*.343)/2;
Serial.print("Distance = ");
Serial.println(distance);
Serial.println(" cm");
delay(500);
}

king shit

[@ybasyionnamishka8773]

will this work on infrared sensor?

[@ScienceFunInnovations]

I haven't used infared sensors, so I couldn't tell you for sure. Sorry!

[@sanjogbelose943]

will this project work with arduino nano ??

[@ScienceFunInnovations]

Yes. Arduino UNO and NANO use the same pinouts, so the code switches over nicely.
