Precise LC Meter on PIC16F84A microcontroller
Almost every multimeter has ability to capacitance measurement ability, but inductance measurement is included in more advanced or specialized multimeters. Especially if you like to work with RF technologies, power supplies, LC measurement capability is vital. Instead of buying one I suggest to build one and have pleasure to use accurate LCD metter built by yourself.
Design is very simple so it is easy to replicate. It can measure inductances from incredibly small inductance 10nH up to 100mH and capacitance from 0.1pF up to 900nF with auto-ranging capability. Information is displayed on 1×16 LCD module. Zero out button allows to set initial inductance/capacitance for precise measurement. Project page has detailed description on developing LC meter and putting in to nice box. All you have to do is to assemble circuit and flash the program. If you have some troubles in building it, you may buy kit with preprogrammed PIC microcontroller.

Hi I like the LC meter Project but the link for program (LC_METER.hex) is not working. plz help me to locate it or suggest another solution.
Seems that they are selling a kit with preprogrammed chip here:
