Here is a motor speed sensor module, ... The Encoder Disc. ... After construction and pre-flight test, the module was connected to an Arduino board and measured the rotation per minute (rpm) rate of a ...

Of course the problem is that the sensor raw data may be as low as 400 counts per inch, and when moving slowly, let’s say an inch a minute, you only get a blip up every 150 milliseconds.

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″).
