Lidars (LIgh Detection And Ranging) measure distances by illuminating the target with laser light and measuring the reflection with a sensor.

This is my 3D Lidar:
This repository contains the source files to build it:
- Mechanical: STL files for 3D-printing, linkages bending patterns and SolidWorks source files,
- Electronics: circuit diagram,
- Arduino code: the Arduino project for the micro-controller,
- Processing code: the LidarViewer Processing sketch.
