Hi,
I've tried to design a circuit using a Light Dependent Resistor in parallel with another branch that is connected to a transistor. When it is dark, the LDR resistance is high, and the current should pass through the branch parallel to the LDR and hence through the transistor. When it is light, the LDR resistance is low, and the current should pass through the branch with the LDR and not the branch with the transistor.
The problem is, I can't make it so that current only flows through one branch. At the moment, it either flows through both branches regardless of the light level or only the branch with the LDR.
The schematic is below.
Any suggestions would be appreciated.
Thanks for helping me out.
