The project is designed to measure frequencies ranging from 1Hz to over 2 MHz by using the 20-pin ATtiny2313 microcontroller. A standard HD44780 16X2 bright white text and blue backlit LCD is used to ...
This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing the ...
