Arduino & LM393 Inductance-meter!


Lately I have been working allot with inductors, ex: DC/DC converters and had a problem not knowing the inductance of most coils I worked with so I decided to build an inductance meter using Arduino and LM393 Comparator. I found the AVR  LC meter with frequency measurement  project by Kerry D. Wong very helpful, it made me understand the concept behind the measurement . The schematic and Arduino code based on similar project by  ReiBot.orgThis meter is not very accurate compared with profesional ones but it does the job.
Update: A better Arduino sketch by ultimoistante:  code here
