Arduino Radar Project

*NEW* Updated version of the code to fit any screen resolution.
I will show you how you can make this cool looking Arduino Radar using the Arduino Board and the Processing Development Environment.

I used this video to make this. I’ve been using these kind of projects to help me through mental health problems. Doing things like this help me forget about negative stuff and focus on making something cool.

Thank you for this. It means more than you realise.

I spent 11 hours and could only come up with 1/100 of what you have displayed. It is a top of the line Sketch that I have seen so far, and very intuitive, making an autonomous robot has become fairly possible and simple . Thank you for sharing You are a gifted individual, Thank you

[gaius_enceladus]

This is very cool!
A couple of suggestions for similar projects -
1 - an Arduino *sonar*. Would be very cool to test on a local lake!
2 - an Arduino ground-penetrating radar. Would be awesome for learning about local geology and maybe even finding fossils!

This is NOT a RADAR (RAdio Detection And Ranging) but a SONAR (SOund Navigation And Ranging).
Radar system operates in UHF or microwaves.

Great! It's works ...I'm 62 years old, and I am happy like a child...with this toy ...thanks!!!

Love this project! I made a similar radar with 4 ultrasonic distance sensors in 4 directions and changed the servo to a stepper motor, and 3D printed the case.

I should have been doing this rather than playing ps3...

Really cool project! Here's an idea for you; convert the sonic sensor to a lidar sensor. Lidar is much more accurate so in theory you would be able to map the room on one plane(unless you add another servo for vertical panning) by keeping track of what angle your sensor is facing (theta) and multiplying the sine and cosine of the angle by the distance measure to find the components of vector displacement from the sensor. Then you would have visible room dimensions mapped out!

I don't know how to thank you. you are the best, keep up the good work

[hippopotamus]

The code you use to calculate the distance is what I found online, however if you put it in a for loop 100 times and average out the readings, it is far more accurate.

[hatem]

You projects are always out of the box. Perfect.
Your processing tutorial 06 is not enough, wish you make more on using it, explaining the most important functions

[josephkitchen]

As someone that is pretty new to arduino you make this very clear and accessible. Thank you!!!!

[wing]

Even though this has been online for 8 years or so this still looks cool and is a great project to practice data transfer through a COM port. I just built it for myself for fun. Thank you.

[RadioAmateurUK]

I have just built this as my first Arduino project. Thank you for posting, it is fantastic!

[tomaims]

Great project! I like how you built the code and described it. I look forward to recreating this project.

[pablofernandezsilva]

Thanks man you speak very good for me i am a spain teenager who has fourteen years and i can understand you, thanks for speak slowly

Best learning platform for everyone thanks to "How to Mechatronics"

Imma make a little "iron dome" to protect my workspace from paper airplane drones XD

[burritotrap]

+Papy Nova (Kamo) I think he used it to keep it simple. The servo can just be clamped to +/- and the third pin to a digital out of the arduino. The servo only needs a PWM signal which you can create with a plain arduino without any other ICs.

For a stepper motor you need an IC/driver hardware which drives the motor which is basically the motor shield for arduino. You can also do some funky stuff with ICs on your own cause it draws too much power to directly source it from the digital or analog outputs.

Air temperature affects speed of sound but only a little per +/- 5C.
Still, go measure outside when it is -10C or colder with formula for +20C indoors.
