Measuring Distance Using Ultrasonic Sensor


In this project I’m using an ultrasonic sensor that can precisely measure the distance to show how a beep sound come out when a car is reversed.  You will noticed that when the car is too near to the barrier behind the car, it will give a continuous beep sound. Let’s figure out how it works!  

Hardware Preparation

This tutorial use :

  1. Maker UNO
  2. Low Cost Ultrasonic Ranging Module
  3. Male to Male Jumper Wire
  4. Micro B USB

You can make the hardware connection based on the diagram and table below.

Ultrasonic Sensor : VCC Maker UNO: 5V
Ultrasonic Sensor : GND Maker UNO: GND
Ultrasonic Sensor : Trig Maker UNO: pin 11
Ultrasonic Sensor : Echo Maker UNO : pin 12
