I've just started playing with electronics, and wanted to make a light/dark detection circuit without using a transistor (they are too advanced for me at this moment.)
I decided to use these components:
- LED
- 10k Resister
- 9V battery
- LDR
I want my LED to turn off when I shine a light on the LDR. I also want my LED to turn on when I cover the LDR. But this does not happen. I'm not sure what is wrong.
