Summary of PIC16F628 LC METER CIRCUIT
This project describes an LC meter circuit using a PIC16F628 microcontroller designed to measure inductance and capacitance values digitally. It features automatic measurement with 4-digit resolution, covering capacitance from 0.1pF to 800nF and inductance from 10nH to 70mH with ±1% accuracy. Operating on 9-12V DC and drawing less than 20mA current, it offers portability via a 9V battery or external power. The device includes an LCD display for reading measurements, making it a cost-effective tool for precise component testing.
Parts used in the PIC16F628 LC Meter Circuit:
- PIC16F628 Microcontroller
- Inductor (various ranges)
- Capacitor (various ranges)
- LCD Display

LC meter circuit made with 16F628 microcontroller can be used to measure the inductor and capacitor values.
Despite its modest cost, it offers automatic direct digital measurement over a wide range for both capacitance (C) and inductance (L) with 4-digit resolution. In fact, it measures capacitance from just 0.1pF up to 800nF and inductance from 10nH to 70mH. Measurement accuracy is also surprisingly good, at better than ±1% of reading
It also operates from 9-12V DC, drawing an average current of less than 20mA. This means that it can be powered from either a 9V alkaline battery inside the case or from an external plugpack supply
