Story

Have you measured the distance to a place? Is your answer yes? Don't you find the task of measuring distance boring? Well I find the task of measuring distance boring.

This is a very simple and easy project. With its help, the distance of any place can be measured very easily. Now the time is slowly passing when people could measure distance only by measuring tape. Now tape has been replaced by such electronic devices which tell you by measuring the distance within a few seconds. This project has also been made for the purpose of distance measuring only. This device can quickly tell you the distance measurement of any place easily. The purpose of making it is that the distance can be found quickly, accurately and easily in less time.

I thought of making this project because of finding the task of measuring distance boring.

That's why I decided to work on such a project and try to make a device with the help of which we can measure the distance even while standing in one place.

The working method of this device is very simple which can be easily understood by everyone.

Ultrasonic sensor plays the main role in this, with the help of which it is easy for us to measure distance.

The ultrasonic sensor has a total of 4 pins. In which 2 pins are for power supply +5 volt and ground. Two more pins are Trig and Echo. The ultrasonic sensor is triggered through the Trig pin, which emits a sound wave with a speed of 340 meters per second in the Air. When the sound wave hits an object and comes back, the Echo pin receives it. The next task belongs to Arduino. Arduino reads and processes that wave and according to the program we get an ideal output

Although I have made this project for the purpose of measuring distance, the output will be visible on the 16x2 LCD screen.

You need these things as main hardware.

1. Arduino Uno R3

2. HC - SR04 Ultrasonic Sensor

3. 16x2 LCD

4. Breadboard

5. USB A To B Cable

6. Male to male and male to female jumper wires
