Really 99999 RPM? Fidget Spinners: Using lasers to measure RPM (DIY Arduino tutorial)

Ever wanted to see how fast your fidget spinner can spin? Want to count how many times it spins before it stops? Can it do 99,999 rpm? I’ll show you in this video how to measure the speed, rpm, total rotations and other stats of your fidget spinner! This video is a DIY video to make your own RPM meter with Arduino and a laser pointer. This is a great way to measure your spinner tricks, or even make a baseline for your spinner against your others. Buy Fidget Spinners: https://amzn.to/2A1JMS7 WARNING: Please do not do this at home. If the fidget spinner comes loose, it can be extremely dangerous! I wore safety goggles and used a clamp. How does it work? Well, it’s very simple, as the fidget spinner spins, it cuts the beam of the laser pointer. The light sensor picks up this change, and it can calculate the speed of the fidget spinner by the rate at which the hand spinner cuts the beam, neat huh? The code itself is simple, and you can download all you need here: https://www.dropbox.com/sh/8wuyl1bkdk60f2h/AADagHX5tFhb1xcnuIdvAFlJa?dl=0 I wrote all of it myself, so feel free to make a comment if you’ve got issues or suggestions!
