This project brings your car's engine to life with a real-time RPM display on a 7-segment display using an Arduino Uno and a SparkFun UART board. Take it for a spin and see your engine roar to life ...

Create an RPM counter (tachometer) with Arduino using an IR sensor and LCD module. This project calculates RPM based on sensor interrupts and displays the result on a 16x2 LCD. Perfect for measuring ...

A tachometer used to be an accessory added to the dash of only the sportiest of cars, but now they’re pretty much standard equipment on everything from sleek coupes to the family truckster. If your ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

Hello everyone! Today I’m going to discuss a cheap type of useful digital rotation per minute counter (Digital RPM Counter). The 4-Digit LED Display RPM comes with a magnetic proximity sensor switch.
