Garmin Lidar Lite Range Finder

A new guide in the Adafruit Learning SystemGarmin Lidar Lite Range Finder

In this guide we will build a range finder, or electronic tape measure if you like, using the new Garmin Lidar-Lite. This is a laser based distance sensor that works by bouncing a modulated laser beam against an surface and measuring how long it take for a reflection to come back.

LiDAR (an acronym for light detection and ranging) is a technology that measures the distance to a target by shining a pulsed laser light on it and analyzing the reflections.

The Garmin LiDAR Lite is a simple, non-rotating sensor that measures the distance to the target it is pointed at.

Autonomous vehicles (i.e. self driving cars) often use LiDAR to map out the space around them.
