Actual image of this project given above, let me explain features of this easy Arduino project

Uses ultrasonic sensor to detect obstacle Display screen shows measured distance of object

Units are in both centimeter and inches Display screen brightness can be increased or decreased using variable resistor embedded in breadboard

Entire System is portable means you can carry it anywhere

Note: Video link for this project is provided at end of this post make sure to check it out, if you are making this project make sure you read all the points.

With all the features being said let’s head on to building this project

Material required to make Arduino Distance Measurement project

Arduino UNO, Display module( LCD Type) and Ultrasonic distance sensor aka HC-SR04

Variable resistance 103, Jumper wires and breadboard and DC Plug attached to rechargeable battery

Arduino IDE Additionally you may require rubber bands and zip ties for finishing everything

Arduino Distance measurement Code

Download and paste this code on your Arduino IDE and later upload this code to your Uno, make sure to check for port number while uploading code, Distance measurement limit can be changed in code

After uploading code disconnect USB Cable from computer and start making circuit, i have provided detailed circuit diagram below for this project

Make sure all the connections are made as per the diagram shown above, for clarity i will be giving detail explanation of circuit

LCD Display module has following pins with its functions

  1. GND means ground
  2. Vcc for 5v power supply
  3. Vo Display
  4. Rs Register
  5. R/W Read/write
  6. E Enable
  7. 0 and 1 are Data pins
  8. A Anode
  9. K Cathode

Display module connections

Gnd will be connect to enable and cathode along with one leg of resistor to Gnd of Arduino Uno

Vcc to anode and other leg of resistor to 5v pin of arduino,Vo to leg of resistor and Register to D12

R/W to gnd of uno and resistor while Digital pins to D2,D3,D4 and D5 Uno pins

After connections are made for Display continue with making connections to Ultrasonic sensor

Vcc and Gnd of sensor will be connect to 5v and gnd of Uno, Trig and Echo to A4 and A5 of board

Once all these are complete just connect Power supply to your board using dc pin supply to which rechargeable batteries are attached
