An easy and effective way to detect rpm's || using an IR Optical sensor

In today's video, I'll be showing you how to detect those rpm's - using an infrared optical sensor. Keep in mind that this is only one of many ways to count revolutions, but in my opinion it's an insanely easy and practical method. Here are all of the parts:

IR optical sensor:


resistors:


lcd module:


arduino uno:


breadboard:


code with lcd:


code using serial.print:

Tachometer,rpm,
