How to Make Mini Radar | Arduino Based

$2 for 10PCBs (24 Hour Fast Build): https://jlcpcb.com

Hello friends in this video I have made a Mini compact Radar with display, for that I have used HC-SR04 ultrasonic sensor, this sensor emit ultrasonic sound which came back to sensor after reflecting from an object,

all the data visualization is displayed on 1.8" ST7735 display, if any object detect by radar it'll show in display in red line.

For this project I have develop a custom made PCB and get it manufactured from JLCPCB.com

JLCPCB is one of the top leader in PCB manufacturing.

Step 1: Video

Have a look to this complete tutorial video

Step 2: Material Required

There is four main components of this project

Arduino nano is the braing of our project

HC-SR04 is ultrasonic sensor this sensor emit ultrasonic sound waves which human can't listen , this sensor generate some value in proportion to the reflected ultrasonic sound waves from the object, on this we can also tell the distance of object from the sensor.

SG90 micro servo is used to rotate ultrasonic sensor in 180 deg

ST77535 display is our monitor to visualize all data on screen

Step 3: Circuit and Code

Code and other details are found on the link

Step 4: 3D Files

Complete 3D files will be available at thingiverse

I have a Tevo Tarantula printer i have printed all parts on dark green PLA at 50 % infill

After printing all the parts or you can design your own model

if you don't have access to a 3D printer then you can use material like acrylic sheet or cardboard sheet.

Do the wiring as shown in circuit drawing and load the code to arduino.

You radar is ready to work if you face any problem please feel free to comment below

Is it possible to get the gerber file you used to make the green board?

HELP ME PLEASE!!

[halfoudari3]

when i compile it to arduino this error is what i get

[halfoudari3]

i want to do this on an ordinary arduino, can you help write the code for me?

please contact me at [e-mail] or whatsapp [phone] for payment.

so....did you figure out you were missing the library or did you miss the deadline for your grade? The error code tells you exactly the problem, next time, as a first step, type the error code into google. Then realize copy and paste exist so you didnt actually have to type it letter by letter. Do you often just buy your way out of trouble? Geez, I sure hope your not studying to become an architect or something.....

RADAR - RAdio Direction And Ranging. It does not use radio, it is not radar. It uses ultrasound. Its SONAR - SOund Navigation And Ranging.

For the love of STEM, USE THE CORRECT TERMINOLOGY INSTEAD OF CLICKBAITING!!! Inspiring newcomers to use incorrect terminology instead of learning the technology involved makes for muddy communication. And science is where cmmunication should never be muddy. Do better, be better, stop with the simplified incorrect wording. And that is to all makers, not just this OP.

I will say, I dig the display.

It seems that the 3D print files are not complete. Any idea where I can find the base? thx

[rmznaydemr]

link yok?

I want to make same project with ILI9341 TFT LCD display and adruino nano. Please let me know if there is any change and how to connect display with adruino. Thank you very much..

[trimbandit]

Is it just me, or does the display image appear to be reversed? like when the sensor is rotating left, on the screen you see it rotating right.

I like how the enclosure makes the sensor look like eyes. :)

thanks
