LC meter DIY project is an Android app developed by NECO that allows users to measure inductance, capacitance, and resonance frequency. This wireless LC meter is a handy tool for electronics enthusiasts and hobbyists.

Using the app is simple. Users need to build a small circuit, which is easy to assemble, and connect it to the capacitor or inductance they wish to measure. Then, place the smartphone near the LC meter circuit, choose the desired measurement (inductance or capacitance), and press the play button in the app. The app will detect the sound frequency from the buzzer and display the corresponding value.

The LC meter has a wide measurement range, allowing users to measure inductance from 100uH to 100mH and capacitance from 10nF to 10uF. Whether you need a cheap and easy-to-build LC meter or want to enhance the circuit by adding different reference value capacitors and inductance, this app is a great solution.

To build the circuit, you will need the following components: Capacitors C1, C2, C3, and C4 (470nF), Inductance (10mH), Transistors Q1 and Q2 (BC557), Resistors R1 (10K), R2 (100), R3 (220K), and R4 (5.1K), a 3-pin switch, and a buzzer.
