I have now concluded my testing of the light detection during sunset.
It looks like this:
So a 10 uF capacitor will cause a time constant of about 500 ms at roundabout dusk.
And that should be measurable with good enough accuracy in a GPIO read loop waiting for a high level I believe.
So can an RPiZero safely discharge a 10 uF capacitor through a GPIO output set to low level without using a series resistor?
It looks like this:
Code:
