Project Overview “In this Instructable we’re going to build a budget spinning LiDAR sensor, powered by Arduino. It cost less than £30 to build ($40) and has a diameter of only 30mm (1.18″).

LiDAR, also known as Light Detection and Ranging, uses lasers to measure the distance, shape, and orientation of 3D objects. LiDAR is becoming increasingly common, appearing in devices like the ...
