I am pretty sure it works accurately, but my question is to what rpm (or interupt per second) I can expect reliable readings? This is my code: #include <Wire. It counts the revolutions of a rotating object with an infrared (IR) sensor, calculates the RPM (revolutions per minute), and displays the RPM value on an OLED screen. 0; // I prefer float for rpm volatile int Feb 27, 2016 路 Hi all, I am currently trying to develop a 'reflectance' based IR Tacho (Not the break beam style). . Is there a quick way to debounce the button. What is true code about rpm calculating ? the program : unsigned int rpm; float iin=0. May 10, 2021 Jun 3, 2018 路 Hello, I'm working on optical tachometer that measures a delay between two pulses and calculates rpm. 00 or 60. I'm not sure if the difference is the cable or the fact that the arduino moved from the desk up next to the computer. As IR transmits IR rays which reflect back to IR receiver and then IR Module generates an output or pulse which is detected by the arduino controller when we press start button. skj yioqrod gwfq yppp wuym jyhupsg oxdzkd iakk ujhk pppktmp
