I have capacitor bank 0.24F 400V. I need to check capacitance periodically. I am able to find code for capacitance meter https://www.arduino.cc/en/Tutorial/Foundations/CapacitanceMeter
The code and schematic seems to be suitable for low voltage capacitors (not sure) becuase capacitor shown is being charged by Arduino supply (5V).
In my case (400V), i can use divider circuit to charge capacitor bank with suitable power supply and read corresponding voltage at analoginput to charge up to 63%. However, i am puzzled whether arduino uno can handle discharge current or 5V is sufficient to measure capacitance or do I need to make some changes in hardware or schematic to achieve this.
