Hi, everyone,
I would like to measure current in a range of 0-500mA (DC) at 3-24V,
whereby time does not matter (each measurement can take 1-2 seconds, so nothing high-frequency).
The results are floating slightly, depending on other stuff running on my Uno rev3,
and I think it might be a good idea to use the LM4040 to create a very stable Vcc.
Do you think that could help?
Best regards
Michael

Re: Ina219 and LM4040
Not really enough information to go on. What else might be drawing current in addition to the UNO? What code is the UNO executing?
