About this document

Arduino RPM Tachometer Project Guide by Diego Mendoza Ancalla is a document available to read on EtoBox.

This document describes how to build an Arduino tachometer to measure rotations per minute (RPM) using an infrared transmitter and receiver. It uses these components along with an Arduino board and 16x2 LCD display. The infrared break-beam is interrupted by a computer fan placed between the transmitter and receiver. The Arduino counts interrupts to calculate RPM using timers. It displays the results on the LCD. The circuit and code are provided to count interrupts and update the display with a smoothed aver
