Check out this video on how to use the data (angle and distance) to draw the points of obstacle.
Hope this is helpful.

Wonderful 💕 nice Sharing...✨ 😍Like 👍 👍 👍

Thank you for uploading the video, the code. You really help me to start my project

[timothycleytusgultom]

hi, can you tell me the name of the communication wire you use to connect the RPLidar with the Arduino? The pins on my RPLidar are too small for me to use jumper wires

is it possible to work with rplidar a2 ?

[ilhamfakhrul]

Hii, can I ask something?
Why my lidar is sending the data so late? Not as fast as in the video

Hi, I am trying to figure out how to work an rplidar I got. I've got it set up with a arduino Uno and I can run simple start and stop but I'm having trouble getting it to output the distances and angles that it is measuring (I tried your code but it gives me some errors). Do you have any ideas what might be going wrong?

I have to use it on UNO the program uploads successfully but lidar does not work even the motor does not rotate what could be problem

Hi -
for initial tests of a RPLidar A1 with an Arduino Mega 2560 I am using all files from your link UNMODIFIED.
Library is OK, but the compiler is complaining: Collect2: error: ld returned 1 exit status
Any idea what is behind this particular error ?
The net is full of numerous and totally different answers & hints concerning this error message ... not really useable.
Thanks a lot for a brief hint from your RPLidar perspective.

How to know the distance of every 1° angle of the lidar or anything. When i tried the code, it's just showed the angle that have a change in distance

I read data from lidar A1 by esp32 same you, but if I simulation it in Rviz2, many point don't appear, Can you solve it ?

[jeevg]

Hi there! I was hoping you could help me please! I am trying to also get data for distance and angles using exactly the same setup. I tried to run your code, is there a command that I need to send through the serial monitor to start scanning? I also made my own code which is similar to yours however I dont have the if and else loops but rather just the start scan command, analogWrite to rotate the motor and then a command obtaining the distance and angle value through getcurrentpoint and then printing that to the serial monitor but that always plots 0 for some reason? Any help would be greatly appreciated! Thanks!

[bernardwilkie]

Hi, could you offer any tips as to why the "If (is_ok(lidar.waitPOINT()) {" may not be running?
Documnetation say this is responsible for reveiving data nodes, cant imagine why its not working. Same exact setup as you.

void loop() {

if (IS_OK(lidar.waitPoint())) {


Thanks in advance for any help.

Excuse me sir, I want to ask, How to measure distance using LiDAR A2M8 with arduino?.

I've tried like the tutorial but with the A2M8 LiDAR type it can't rotate

[amratkumar]

bro i am unable to add rplidar library in my arduino ide, it is showing error when i am adding the library can you please help in solving it
