[MOVED] Light dependent resistor

[Bhuvanesh123]

if we connect ldr to one of analog input pin.does the change in resistance converted to digital value or the voltage which changes by potential divider circuit converted to digital value or niether.

Re: Light dependent resistor

both are related but essentially the voltage output of the potential divider circuit will govern the digital value produced by ADC.. but if you closely observe the situation the change of voltage was caused by change in Resistance of LDR ..so both are correlated .
