Digital LC meter

One of the selfmade tools I frequently use is a digital LC meter.  With this device it is very simple to determine the value of an inductor or capacitor. I built this nice design in 2011 according to the description on this website

The required HEX-file for the PIC can also be found here.



In an earlier version, an external comparator LM311 was used. With this design the internal comparator  of the PIC16F628A is used.
