It's easy to use the Arduino as an accurate inductance meter or capacitance meter. I show here the use as inductance meter. To use as cap meter you basically use the same circuit but put a reference inductor in place of the reference capacitor in the circuit's test tank, and change the math around a little bit. Display of data can be done in the serial monitor, you don't need the fancy LCD screen obviously.

Found that site : http://www.kerrywong.com/2010/10/16/avr-lc-meter-with-frequency-measurement/

but I'm not sure if that similar version is working good... although it has a nice feature of calibration.
TinselKoala, can you merge both circuits to prepare one able to measure frequency,inductance, capacitance and maybe also parallel tank circuit frequency (external RCL circuit with the method of kick into ring down oscillation and count peaks as you described in some video) ?
That would be really useful device !

Very nice. thanks for that.

I chose the 2.8 touchscreen for the ability to do and show many things at once on the screen as a stand alone unit without the pc connected. My WattsUp meter uses a a 2 row display and flashes back an forth between other parameters like every 2 seconds or so. I just wanted more with the possibility of even a tiny scope in the corner along with other updating info. Im happy with what I can do with it.

Will be interesting to see how the inductance meter reads across 1 strand of these bifi coils compared to both strands in series. The cap meter test of the winding vs both windings in series shows the same reading. Checked and double checked. We will see.

Thanks Forest     More is better. Like the turns of a bifi.
