SPDCHECK, this is an LDR. I am sorry for the mix-up. So what I want to do is like you said, using wire to switch on the LED when it becomes dark. Does this take the same role as a resistor would if it were used?I too cannot understand what exactly it is that you want
Firstly, I personally always thought a “Photocell” is the same as a solar panel cell (something that generates a voltage proportional to sunlight exposed to the cell). What you list here as a ”Mini Photocell” is what I know as a LDR (Light dependant resistor). Just clarify that for me, is this an LDR as I know it, or a solar cell??
Secondly, if it is an LDR, do you want it switch on the LED (using a 3V battery) when it becomes dark, or do you want a circuit that uses a “Solar Cell” to charge a 3V battery?
