1Hz to 10MHz frequency meter using ATtiny2313
|
|
This AVR-based Frequency Meter is capable of measuring frequencies from 1Hz to 10MHz with 1 Hz resolution. The hardware of this project consists of seven 7-segment displays, AVR ATtiny2313 uController, and a few transistors and resistors. The AVR counts input pulses for a precise 1 second interval (generated using the built-in Timer) and displays the result on the multiplexed seven segment LED displays.

Hi Raj!
I am thinking about developing simple project which can take readings for breathing rate. Can you help me with an idea where to start.
Thanks
