May i get The basic ideas for it
And may i get some useful Links

There is a 16f628a version.
Code, pcct and details.

The 80µh coil can be had as free sample from CoilCraft.
Max.

Hey! Give me a chance to plug one of my web pages... 
This one does not require a precision inductor and needs no relay. A stable 1,000 pf capacitor is needed, preferably with a 1% tolerance, the capacitance is used to calibrate the inductor.
Not believing PIC or AVR is superior overall, I point out that this project uses an AVR controller.

One thing that many people discover about the oscillators of the kind used in the links that MaxHeadRoom provided and in my meter, some after making the PC boards, is that if the inductor has too high of a resistance, the accuracy will suffer when measuring large value capacitors. Whichever of the versions you make, get the lowest resistance you can.
