Hi
I like to see if I can monitor the strike voltage on a lamp by a ballast, the strike voltage is about 1400V, using R1 to be 1M ohms and R1 to be 2.2k ohms on the divider I should see about 3.0V on the MCU's ADC pin, this looks workable but the most I have tried and seen working was 300V in theory this should work. Anyone have any experience on this?
