What is the difference between them?
Can they be used the same way?
So, it is about the same idea as Photoresistor Voltage Divider Circuits shown in the photosensor tutorial right?
the Vin I use is 5volt from the power supply and Vout should be 5volt to the PIC right? Or how much should i expecting my Vout? So, based on the formula (R*Vin)/(R+Rphoto) = Vout, my R will be zero?
