Hey,
I need a simple circuit that can activate an LED from a Light Detecting Resistor(LDR). The main problem is i need the LDR to be up to 40feet away on a cable and to be able to activate the LED preferably inside a small box from that distance. I also need this all to run off 12v-dc.
To be honest i'm not that clued up, so the specifications/modelno. of resistors and components that can be purchased off RS would be a great help.
Many Thanks.
Alex
