Inductor & Capacitor Meter (LCMeter)


    Here is my new inductance & capacitance meter. I had took the analog oscillator part from a well know schematic found on the internet and adapt it for a AVR.  It's impressive to have a very accurate result with a so small circuit.  The way it's work is simple you chance a oscillator frequency with the part you want to find is value.

Frequancy Meter


Here is my new Frequency meter who was done with a LCD's cellular phone!!!  This is a simple project. The Frequency is passing  through an op-amp to convert it in a square wave. The ouput of the op-amp is feeding the 3*8 bits counter (24 bits) who can accumulate at a maximum of 16777216 count.
