RPM-meter-arduino Simple code for Arduino Project I made. Using Hall-Effect Sensor we can measure the speed of rotation. RPM (Revolutions per minute) – the number of revolutions per minute.

This is a tachometer, counter, and current meter for the LMS 5200 mini-lathe, LMS 3990 mini-mill and similar tools that use the XMT-DRV-500C (3) / ZM3404 BLDC motor controller. This project provides a ...

The parts arrived for the RPM meter that uses an Arduino and reciprocal counting to get a three-times-a-second update rate with 1rpm resolution. Arduinos ...
