I don't know why my LEDs won't light up

First make sure your wiring matches the provided sketch. If that doesn't work, try running a basic LED project to check if the LEDs aren't faulty nor broken, or try replacing some of the components such as the wires, resistors, or even the LEDs with new ones. Hope this helps!

can you send me this stand for ultrasonic sensor and servo?

you can just glue the sensor onto the servo

I bought the stand a long time ago so unfortunately I can't give you the exact model used in this project, I just came across it when looking through my Arduino things. However, you can search for similar stands on Google or Amazon. Mine came in a small Servo pack, which essentially gives you small accessories for your servos.

As for the base of the radar, I just attached the Servo motor stand to a random empty box.

For some reason all of my LEDs are on when my machine is on and my buzzer doesn't beep

A great number of factors could cause these errors, I'll try to cover the most common ones. For the LEDs make sure the wiring is done correctly and that there are no short circuits, because that can cause the LEDs to be turned on continuously. For the Buzzer I highly recommend running a very basic Buzzer project to make sure the component isn't faulty or damaged. If nothing else works you can try replacing the components or the wires. If you have any questions, feel free to ask :)

I understand how the electricity runs through the passive buzzer but I don't know why my passive buzzer doesn't seem to be working

You should first check the wiring for the buzzer. If everything is wired correctly try running some simple test programs from the internet before uploading the radar code. If you follow these tips you should be able to find the issue. If the issue is still unresolved, feel free to ask me or the community on Reddit.

How did you mount the ultrasonic sensor to the servo? Did you use a 3D-printed part, or do I need to purchase something?

Sorry for the late reply, but the black mount for the radar came with a servo motor pack I found on Amazon. You can search for Arduino servo motor kits and you should find one that includes some kind of mount.

I have a starter kid and was wondering if there are any substitutions I can use because I don’t have a slide switch.

The script generates a single sweep per action. With that in mind, you can use a simple button. A single button press will start the sweep which will continue until the loop ends. Pressing the button again will start the loop again. I hope this helps =D
