Description

Manually calibrated Franklin oscillator LC meter

This LC meter is based on the Fraclin oscillator and Arduino controler. The frequency difference is occured by put the sample parts of the inducter or the capacitor. Arduino shall calculate the value to solute the equation. To recognize such mechanism by assembling and operating this equipment, it is useful for getting the acknoledge of the electronics. Also this meter shall be nesessary to measure the self wound coil value.
