interesting project. Do you know or can you tell me how to find out the input resistance of such a meter? ?I don¡¯t seem to find it on the Arduino spec sheet.?
When building an RF probe the series resistor is calculated based in meter input resistance. ?Yes, not critical if all you need are relative readings or differential gain/loss measurements. ?But would be nice to have the reading somewhat accurate.?
