The project was developed for measuring frequencies from 5Hz to 500kHz as it was based on the AT89C52 microcontroller. This 500kHz frequency meter is suitable for tracing and debugging most of the ...
The circuit was designed to create a low cost frequency meter that will cover the range of 1 Hz to 1 MHz with a digital indication using three 7-segment displays. 7805 – a 3-terminal 1A positive ...
