Ever wanted to measure with out a scale or measuring tape?

Measure distance Digitally without a hassle with this small device!

Step 1: HOW IT WORKS?

A special sonic transducer is used for the ultrasonic proximity sensors, which allows for alternate transmission and reception of sound waves. The sonic waves emitted by the transducer are reflected by an object and received back in the transducer. After having emitted the sound waves, the ultrasonic sensor will switch to receive mode. The time elapsed between emitting and receiving is proportional to the distance of the object from the sensor.

Step 2: COMPONENTS

>ARDUINO UNO (Buy From Amazon.in) (Buy From Amazon.com)

>ULTRASONIC SENSOR HC-SR04

(Buy From Amazon)(Buy it from Amazon.com)

>16*2 LCD SCREEN (Buy From Amazon.in)(Buy it From Amazon.com)

>POTENTIO METER [ADJUSTING CONTRAST OF LCD]

(Buy from Amazon.in)(Buy it From Amazon.com)

>9V BATTREY (Buy from Amazon.in)(Buy it From Amazon.com)

>CONNECTION CABLE (Buy from Amazon.in) (Buy it from Amazon)

> Header Pin [optional] (Buy from Amazon.in) (Buy it From Amazon.com)

> Glue Gun [optional](Buy from Amazon.in) (Buy it From Amazon.com)

Step 3: HEADER PIN

Use header pin so that You can easely make this project using only MALE TO FEMALE & FEMALE TO FEMALE JUMPER WIRES

Step 1: Place the Header Pin into the pins of Arduino After it glueing it will look like this.

Step 2:Using GlueGun, Glue the header pin to Arduino so that it does’nt become loose.

Double check whether the header pins are not loose,otherwise there will be no output from the pin!!

Step 4: CIRCUIT

CONNECT ARDUINO ACCORDINGLY!

LCD Connection

D7- DIGITAL PIN 2

D6 – 3

D5 – 4

D4 – 5

E – 11

RS – 12

VDD (+) RAIL BREADBOARD

A (+)RAIL BREADBOARD

—————————————

VSS (-)RAIL BREADBOARD

K (-)RAIL BREADBOARD

RW (-)RAIL BREADBOARD

Step 5: THE BOX

USE A BOX OF MEASURE MORE THAN

13 CM LENGTH

11 CM BREADTH

6 CM HIGHT

USE A BOX OF MORE LENGTH or else everything will be a little messy! (as in the box) 😀

Step 6: MAKE HOLES

MAKE HOLES FOR THE

>>ULTRASONIC SENSOR

>>LCD SCREEN

>>POTENTIOMETER

STICK EVERYTHING USING A DOUBLE SIDE CELLOTAPE

Step 7: KEEP EVRYTHING INSIDE THE BOX!

AS I HAD CHOOSEN A SMALL BOX EVERYTHING SEEMS A LITTLE MESSY!

BE SURE TO TAKE A BIG ONE!

Use a 9V battrey/Powerbank to power the arduino

TIP : Cover the box with some colour paper / paint it

Step 8: DATASHEET

DATASHEET

Please download the ULTRASONIC SENSOR library from the above link.

Then Open Arduino IDE Go to Sketch
–> Include Library

–> Add Zip File Close the Arduino IDE and open it again then you will find the library included.

For more info : https://www.arduino.cc/en/Guide/Libraries

Step 9: Code

Download the Code from the link and open it with Arduino IDE.

Step 10: Done!

You can see the Current Distance from the object in front on the LCD screen….

You can adjust the contrast (Sometimes the display might be blured)by turning shaft of the Potentiometer!

Thats all makers!
