Hi, I’m trying to use a LIDAR module with an arduino Mega using the RX and TX ports of the module but I can’t manage to make it work. I tried to adapt the idea described in this project Capteur de Distance Laser LIDAR-Lite - Croquis Arduino d’Un «Radar» | RobotShop Community but it didn’t worked.
Hope you’ll can help me !

Ps. the Lidar’s reference : https://www.robot-advance.com/art-capteur-de-distance-laser-360-lds-01-2352.htm

Hello @j0hnCen4 and welcome to the forum!

The LIDAR module you linked works with 3.3V while the Arduino Mega works with 5V, you need to use a level shifter.

I hope that helps!
