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.

This is super cool. As an upgrade, you should measure the time of flight to get distance as well as angle like a real radar. Second upgrade, Doppler to get object relative velocity.

[@davea1771]

Technically, this is sonar (SOund Navigation And Ranging), not radar (RAdio Detection And Ranging). We made a similar system back in 1982 using an ultrasonic transducer from a polaroid camera, a stepper motor, and an IMSAI 8080 computer for a college lab course. It's still pretty cool, even after 38 years have passed.

"Added to my DIY to do list" Thanks and nice job !

[@Inventor101]

Man your amazing I love your videos👍👍👍

[@DIYLabs]

Good idea bro, that radar is really good

[@TitansRevenge3D]

Code and circuit link no longer working :(

[@igorovcharov7424]

set the sonar fixedly. And for coverage, apply a synchronously rotating prism in front of it. This will increase performance and reach.

[@matiasecheveste7320]

I have a problem wanting to open the file. Arduino tells me that "the program cannot be created". Please I need help.

[@gamebox-13]

Damn, that PCB is awful and totally useless. You can connect all parts directly to arduino.

[@EvileDik]

I think maybe he is advertising JLCPCB, he always uses their PCB, even when a few Dupont connector would do :)

[@vptech9861]

Let's say that at least it is a good mechanical DIY. Better than all of these hot glue projects that we can see everywhere.

[@goddamnmaddog2024]

because nothing says "professional" as loud as hotglue and ducttape on a breadboard, XD This way, every component is easily replaceable. No need to rewire everything, just plug'n'play!

[@daviking-88]

I'd probably try to make the display sweep in the same direction as the radar unit...

[@h.m.srodney7161]

I thaught using an ultrasound detector made it a sonar ?

[@357d]

I have a small problem. In my country, I cannot print the green board, and I do not have a printer. What is the alternative to the board? I hope for a reply.

[@daviddavidson1372]

where are the Gerber files for the PCB..Thanks.I use jlcpcb before.there great.

[@sarahulrich4952]

This looks really fun. Where can we find the Gerber file to order the PCB? Or can we order the PCB from your website?

[@lolleepop]

Ur github page is not working. Plz reupload the code and send the link

[@electronic7979]

Excellent project 👍 very good

[@KAUSTUBH...]

I am making robotic arm record and play but problem in 2 motors move in 1 potentiometer how to solve this error

[@kandasamy1236]

Kindly send an video like this for Make small satellites.. And wonderful demo .. Done a great job.. Super.. I welcoming these kinds of videos from ur channel.. Thank so much.. congratulations..

[@feelinspiffy696]

wait how gonna charge/change the battery?

[@mntalks9286]

Sir please send the code link I can't get it can you please send it to me please sir pls 🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@sebastianramirezarbelaez8060]

Hola, que programa usaste para diseñar el prototipo?

[@arghyadas5789]

Brother ....is we have to connect the display directly to the board ...???? No need of any programming the display ??? .....plzz reply

[@adityakathirvel6209]

For designing pcbs?

[@nicasionicklaus4142]

I am also trying to do this project but my LCD's resolution is 128x128....what variables in the code do I need to modify to make the graphic fit? thanks in advance

[@phantomthedagger15208]

U r ultra mega super intelligent

[@lordofmech]

Code please link is not opening

[@ThingEngineer]

Just curious, why did you go this far and not display at least slightly inaccurate distance data? That’s literally what those ultrasonic sensors are for.

[@TemporalRecall]

Is the "reflection or no refection" binary readout a hardware or firmware limitation?

[@EvileDik]

Firmware, the Ultrasound unit is capable of measuring distance. The maker did not implement this function.

[@gaeldominguez3647]

thank u so much sir

[@AmirRezssf]

How can I find code and pcb of this project???

[@ashuschandran123]

Wait can we upload the code into the Arduino nano without connecting it with a usb cable

[@Maruchipawa]

No

[@venkateswaraok1647]

What is the maximum range

[@rudolf.szatlmayer]

It is displayed incorrectly. When the sensor is rotating to the left, on the display is drawn to the right. It should be the opposite, otherwise it will render the wrong location.

[@sandeepchaturvedi3232]

Can you repost the code and circuit. The given link is not working

[@ftechshorts6398]

Can you please give me code. Because there is no code in the given link

[@jessybiju6079]

Can i make this using arudino uno

[@elve44]

Je ne trouve pas les fichiers PCB

[@TheSolongsidekick]

Your Github was either nuked, or linked wrong or I don't know but it's gone.

[@quetzalyollotlchavezsotelo3188]

no muestras el programa completo en el video, porque???

[@sariphidayat4837]

How make display for tft ?

[@rishikushwaha4011]

Man where are Gerber files for pcb?

[@burylad4eva]

This is so cool. I dont know much about this but what does it detect?

[@loststudios2432]

But, the radar is mirrored, how do we fix that?

[@invisnikewolf]

Please upload your Gerber file

[@nextronium3608]

What is the starting background music

[@adityakathirvel6209]

Can you please say what software you use ?

[@keithschaub7863]

github code link isn't working?????????????????????????????

[@kyrillossawiris8842]

hello sir, the link of the code doesn`t work

[@TYMCstudiosLittleTY]

This is so cool

[@이준호-f5d]

where is pcb file???

[@miguelurq2886]

Could i use 3,5"tft lcd?

[@pamphilevictorienyamicole2321]

Hi, it's a good project so is it possible to show the graph of the radar without cablebut with bluetooth for example. Thank u

[@EvileDik]

You could use an ESP2866 or ESP32 processeor instead of Arduino Nano, they have built in WiFi and Bluetooth. You could then connect your phone to it.

[@vptech9861]

By the way, I'd like to see the graph on my TV and available from everywhere in the world via the broadcasting satellite network :-D

[@anantyapa8115]

What is the range

[@nextronium3608]

Hi, can I code Arduino nano using Arduinodroid app in mobile . please help me

[@Dommy308]

Whats the possibility of extending the range out, to say 100m ?

[@EvileDik]

The ultrasound unit shown here is only good for 4M or so. You would need an _expensive_ LIDAR unit to sense that far.

[@bashkillszombies]

You need discrimination, doppler and return timing! Or it's not really radar, just a noise maker.

[@Masterminion1]

is that chip requiered?

[@wanglydiaplt]

I see you posted this 4 yrs ago; have you devised an upgrade yet? Looking for a unit that can range to maybe ten meters. :-)

[@AltGyt-bc5yf]

Hello sir good day can you update your code ? We really need this for our project

[@abeljestin1199]

Hey bro Can you please make this using tft 3.5"LCD display and arduino uno

[@domenicoportoso6172]

where is pcb file

[@skeets6060]

Whats the range?

[@Masterminion1]

Amazing video! What is the total price of this project?

[@PradumEEEKumar]

github page is not working.

[@604smit]

nice project!

[@wijdannaufal.a]

Not pcb work?

[@nextronium3608]

Please send me download link of code

[@eranbach3366]

What pcb file have you used?

[@javierlux6257]

very good project and how I would change by adding a 2.4 screen

[@jn1980gaming]

the code is offline... the thingiverse files are not complete... waste of time.

[@yupingliao4078]

Hi everyone, I came across this unit and it reminded me that I used to like this too, now I'm trying the unit , The code link is invalid. It seems that the link to the github platform may have been removed intentionally. I won't say who? But I am really grateful to this author for sharing the code and 3D printing stl data before, so that I can successfully download it to my USB flash drive. I have already printed the 3D printing before (Fortunately, I already downloaded it many years ago), and the code has been uploaded to NANO for testing. The 1.8-inch TFT color screen has been successfully displayed. I haven't assembled it all into the 3D shell yet. Now all the semi-finished products are placed in the warehouse I rented outside. When I have time, I will take them home and assemble them all. I will post them here: " I was the first to success "

[@sheerazfaiz3163]

Brother I want to buy this project plz help me
