# mRPM
This project describes how to make a RPM (rotations per minute) meter.
It uses an ESP8266 (it has WiFi, but it is not used), a 4 times 8x8 LED matrix and a line tracking sensor.
I made this upon request of Jan Ridders (http://www.ridders.nu/).
He needs to measure the speed of his stirling, steam or combustion engines.

The ESP8266 was chosen because it is easy and cheap; this project does not (yet?) use the WiFi capabilities of the ESP8266.
