Most of us like our paths from our car to our door to be lit up. It not only helps us see better but it can make us feel safer. This is especially important when it gets dark so early in the winter. A dark sensor is the perfection solution and you might be stunned by how easy it is to make!
The Step By Step Directions To Follow Are:
1 Order components:
1xLDR
1xLED
1xBreadboard
1x100K ohm resistor
1×330 ohm resistor
1xBC547 Transistor
1x9V. Battery
1x9V.Battery Clip
jumper wires or single strand wires.NOTE: I used 47K ohm resistor instead of 100K resistor cuz I didn't had one. It is better to use a 100K ohm resistor.

3 SUCCESS!
That's it!
This dark sensor is so easy and works so well, you may want to make several more of them! Have you made this dark sensor yet?
