# Tachometer

Simple tachometer, based on arduino nano.

7 digit display based on ULN2003 and 74HC595

3 buttons:

1. Reset

2. Mode switch. Between Hz and RPM.

3. Point position. Chose how many digits after point will be displayed.

This tachometer uses ATmega328p Input capture register of Timer Counter #1.

Also I used a lot of float math in this code. ToDo is to move all math into static point to improve speed.
