Hi.
The intention is to use a NE567 that will turn a LED on when frequency is 60Hz +/- 5Hz and two more leds for frequency being lower and higher.
Does the NE567 has any pin useable to tell if input is under or over the center frequency ?
It is for a adjusting the engine governors in portable generators, to be built in a wall wart case.
