I am looking at this:
VCC <-> LDR <-> resistor <-> GND. And the analog input is between the LDR and the resistor.
I understand than a resistor may be necessary to control the current (in case the LDR resistance is very low). But Why can't I just do the following:
VCC <-> LDR <-> resistor <-> Analog Input
And forget about the pull-down?
