I would like to share the project that I built in these dark days.
I hope it will come in handy!
in the zip file everything you need to build and program it
INDUCTANCE METER ONLY SERIAL via arduino ide @115200 baud
not having an LM393 available, I used LM339, it still works
this is a code that I found online, it works differently from the usual unreliable ones, it is very precise, to give you an example:
real 22uH - 22uH arduino
real 250uH - 246uH arduino
real 390uH - 387uH arduino
real 5MH - 5MH arduino
you must enter the precise value of the 1uF capacitor in the sketch before loading it
code line: capacitance = 1.E-6; //Using 1uF Capacitor (example i use 1.06E-6; )
ATMEGA328P PROGRAMMER
make a programmer arduino uno
open arduino ide
"file - examples - arudinoisp - upload"
if you need to burn bootloader, go to
"tools - programmer - select arduino as isp - burn bootloader"
in the pcb I put two jumpers to connect the 10uF capacitor in case of need, DO NOT leave connected or gives you an error, connect only when it gives you an error
if you receive an error, connect 10uF capacitor positive to 3v3 and negative to reset if not use jumpers
I cut a precidip to measure to connect the necessary quartz and capacitors
for simplicity I use avrdudess but you can also use other programs to your preference
I hope it will come in handy!
