Description
Anything to Clock--LM311 based
I needed a simple circuit to condition incoming signals so a MCU could read them as clock:
--rectify the imcoming signal
--Clamp voltage to 3.3 or 5V (so as to not damage the MCU's inputs)
If you need a precision rectifier to turn audio or LFO signals into a rising/falling edges, this small circuit gets the job done.
