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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
