DIY PIC Microcontroller Based Digital Tachometer Project
Have you ever wanted to determine how fast something was turning? With a few parts and a microcontroller, monitoring something spinning is a simple task, you just need a way to get an input into the microcontroller so it can count pulses. In this case Chris from Pyro Electric used an infrared beam to monitor a spinning fan, as the fan blades turn they interrupt the IR beam made using
