Digital tachometer

I did it last year for pass microprocessors systems class on university. I realized I don't need speedometer, so tachometer in not necessary too - i don't use it anyway

Here's a video

here's pdf in Polish.

Tachometer is based on atmega microprocessors (programmed with code done in C - haven't got already). This project is quite simple, made sooo wrong, but it works somehow

.

It counts time between impulses from engine (interrupter(?)) and display it in rpm x10.
