Hi everyone, i am trying to read the brightness intensity of a light with a photoresistor in series with a 2kHom reisistor and when i read from the analogRead a number between 0 and 1023 but I does not understand what this value means and what is the unit measurement of this value.
In addition I tried to change the resistor in series and i get other values at the same conditions so i think that this value is realted to the voltage splitter.
I want to convert the value that i get into something like lumens.
