Hi can any 1 tell me or show me how to make an LDR circuit on a copper strip breadboard so that the LED lights when the lDR is in darkness thanks. The power supply is from a 9v battery.

here is a schematic

assuming you can read a schematic?
if not then maybe I can draw with boxes etc.
the schematic has a potentiometer in place of the LDR. not a big deal.

I can read that drawing but im still not sure how they would all be placed on the copper matrix board. I have drawn a schematic and in mine I have got 3 resistors the LDR an LED and an npn transistor just not sure where to place them all on the matrix board**broken link removed** that image is the type of board i am talking about exept black strips are copper.
