LiDAR Lite v3 & v3HP Wiring and Programming Tutorial

- Hello everybody! I just received a somewhat of a gift (the lidar) and wanted to learn how to use it. I had some problems along the way, and I hope that anyone that has (or even doesn't have) a LiDAR Lite v3 or v3HP will find this video educational and/or helpful.

Thanks for the idea of using LIDAR. I had forgotten.
Awesome video! Thanks man I appreciate it 👌
the wires respect their color and the arduino program measures your objects at a certain distance?
a servo-motor was ok if you wanted a 180 ° measurement
hi may I ask is there a way to connect 2 lidar lite v3 sensors together on the hardware? I am unsure about the connections on the breadboard
Hey! I want to setup Lidar lite v3 with nodemcu. What changes do I need to make?
Question regarding the "beam", does it spread out significantly at it's max distance? I'm evaluating whether this is a good option to detect clearance height, not necessarily distance. E.g. if a fork lift is raised too high as it approaches a doorway, it will break the beam and flash a red light rapidly. Essentially at any distance this would apply, but ideally the farther back the better. Incidentally, what's that nominal distance? Thanks for the info!!
If I understand you correctly, it would just take some simple math to detect clearance height. You'd have to have a servo motor and account for the angle of the servo, but that's all you'd really have to do.
As for the spread of the beam, I think you may be referring to solid state LiDAR rather than mechanical LiDAR, which is the one used in the video. Solid-state refracts hundreds of beams from one light source, allowing for much faster and broader collection of data. There have been next to no cheap options in the market, so the this one is just a mechanical LiDAR. If you're working on a project of some kind, feel free to update me if you'd like. I love that kind of stuff.
Nice tutorial. I followed all your connections instructions and run the arduino program. It works just like yours. Now, do you have a tutorial about how to get the data from the I2C arduino object and have it read or write to MATLAB? I'm working on a project and need to have the arduino with the I2C (the LIDAR sensor) data sent to MATLAB and plot it or make some type of graph. Please let me know as soon as possible.
I think that the easiest way to do that would be to scan, and keep the scanned data on the arduino and then import them to your local desktop, to then analyze with matlab or unity or something else. You could try connecting the arduino to your laptop or something via serial bus, but then you'd have to print it out and then transmit it, and it's just much slower and buggier than other methods. I did a similar project, except I added a separate processor to the system, allowing for live graphing of data. It got a bit complicated, but it was definitely worth it in the end.
But again, I suggest that you just keep the data on the arduino and then import it to the computer at a later time.
hi script kiddie , can i use different value of capacitor ? such as 47uF or 100uF? really interested on building this project! best tutorials and thank you from Malaysia!
it seems the idea is to prevent the 5v rail from dropping while in i2c mode. Spektrum makes a capacitor for their RC receivers which prevents voltage dropouts ( 'voltage protector' spm1600) , it's fairly small in size but has 4700μf @ 10v. I suppose for this application a few hundred μf is probably the minimum.
how important is the use of the capacitor?
what did u click after u type A?
You have to use heat shrinking tubes mateeee
yes bro i think so too!!! Buy it on RS

The volume was so low that I skipped this one, although it may actually be good.
There’s a button on phones (or key on a computer) that you can use to turn up the volume. Give it a press a few times and that should do the trick. Should do wonders
you menace to society, white wires for ground and power
Except in California.
