Sometimes we need to measure inductance and capacitance, but why buy a tool when you can build it? Phil Rice designed this LC meter with a PIC16F628, 16×1 LCD display, and some passive components. You might be able to build this with components you already have.
wow, nice stuff. woudn’t that be a nice project for dangerous + seeed? But they’d need to use high quality components (the right capacitors and a 10ppm or better oscillator) to make it good.
I’m building this project right now, haven’t get it to work yet, the readout oscillates a lot.
Has anybody succeed in getting this to work reliable?
I took again this project during the week. It’s working now.
Had a bad relay.
Must say that I’m really impressed with the precision, and the range is just what my off the shelf LC meter cannot read.
It’s a great tool to build.

dear sir,
i am final year student and i need the working of LC meter and internal circuit can you help me????????
have you found any help ? because i’m in your shoes right now :p i am a final year student and i need the C source code to work on it
Does anyone have the working HEX file for this? It is not available at their websight….
dear widd;
I’m sorry to say that after searching for month’s, I never did find either a source code or hex file for this project. I believe that they want to force you to buy their product, Sincre then I have constructed several from the internet with varying degrees of success. None of which I would advice without a good pcb. Breadboarding just seems to bring in to much interference.
Sorry, I couldn’t be more help.
Fred
P.S. If you find one that works well, let me know. I have about 4 or 5 that don’t.
