                      Automatic night light sensor

Hi ,,, Every one

welcome to learning times :)

Today we are going to learn about ...

Automatic night light....

first we need some simple parts here

1) resistor R1 = 1k ohm

2) resistor R2 = 400 ohm

3) LDR ( light dependent resistor )

4) trinsistor  3904

5) led                                                                    

connect all the parts as shown in the circuit diagram properly and do not allow the short circuit there . And power the circuit with 6 volt battery .
