A project log for Pi Pico Power Meter

For my electronic developments I need more than one multimeter to get the power. Here it is!

Some Code adjustments made it possible to track the charging power of my old Nexus 10 tablet.

With a button push the data are logged to a csv file. Another press will stop the logging.

For a decade I was wondering why the charge performance is bad. I can see that the charging current is variing all the time up and down.

After I took the photo I added the ground wire to get the voltage.
