Making an Optical TACHOMETER using Arduino and Infrared sensor

Hello Friends,
In today's video, we will learn how to make an optical tachometer using arduino uno and infrared sensor. An optical tachometer is an instrument used for measuring the rotational speed. The infrared sensor detects any movement of the rotating object across it and generateS a pulse. The time between the pulses is measured by arduino and is converted to rotations per minute (RPM). The rotational speed of motors, fans, pumps etc. can be measured using this tachometer. The measured speed is displayed using an SSD1306 OLED display.

Thank you for your really nice video (and very easy to use code) for the project! The project is also helpful because it teaches how to use interrupts. I noticed that interrupts-based counting works very well and fast with Uno board but poorly with Pro Micro (will overcount by a large factor).

Okay..That is true. Thank you for the suggestion.🙂
