Power Line Frequency Monitor

60 Hz Frequency Calibration

This low cost module measures the short-term accuracy of 60 Hz sources. A bright bargraph indicator displays variations around the ideal frequency.

Prototype Photo
The circuit is constructed around a single chip microcontroller with a minimum of external components. A red LED blinks at 1 Hz and the bargraph display is updated once per second with the frequency readout. The prototype circuit requires only a +5V regulated supply and the external TTL level source to be measured.
