LC Meter Based on the AVR Microcontroller
Friday, August 14th, 2009

Calculates and displays L and C from oscillation frequency using reference components. This instrument requires two precision components: A precision capacitor and a precision inductor. You only need to start with one precision component, either the reference capacitor or the reference inductor, and using this meter, you can select or adjust the other precision component. [...]
