Introduction: Arduino Range Finder Tutorial

Make your first project with an arduino UNO or any arduino, and a range finder sensor

Step 1: Make Sure You've Got Everything!

Your gunna need- 4 jumper wires 1 arduino ( I used UNO) 1 breadboard 1 data cable to program the arduino 1 hc-sro4 sensor

Step 2: Plug Your Sensor Into the Breadboard

Put your sensor into the breadboard along with 4 jumper wires.

Step 3: Attach to Arduino

Gnd - gnd Echo- digital pin 2 Trig - digital pin 3 Vcc - 5v

Step 4: Write the Code

Just copy from photo

Step 5: Plug in and Upload

Plug your arduino into your pc and upload. Open serial monitor in top right corner and have fun. You can use this with hundreds of projects good luck

    Thanks supah,

    Minor outputting improvement can be had with:

    Serial.print(distance);

    Serial.println(" cm");

    #define trigPin 3

    #define echoPin 2

    void setup()

    {

    Serial.begin(9600);

    pinMode(trigPin, OUTPUT);

    pinMode(echoPin, INPUT);

    }

    void loop()

    {

    int duration, distance;

    digitalWrite(trigPin, HIGH);

    delayMicroseconds(2000);

    digitalWrite(trigPin, LOW);

    duration = pulseIn(echoPin, HIGH);

    distance = (duration/2) / 29.1;

    Serial.println(distance);

    Serial.print("cm");

    delay(500);

    }

    Nice, simple, very well done.

    Excellent basic tutorial, it helped me set mine up with a minimum of problems.
