Using sensors without Arduino

Apparatus:

LDR Module
LED
Buzzer
9V battery
Breadboard


Procedure:

1)Connect the positive and negative terminal of the battery to the positive and negative of the Bread Board respectively. 
2)Connect the positive and negative of the module to positive and negative of the Bread Board.
3) Connect the output pin of the module to the central breadboard.
4)Connect the positive of the buzzer to the output of the module.
5)Connect the negative of the buzzer to the negative of the breadboard.
6)Connect the positive of the LED to the output of the module.
7)Connect the negative of the LED to the negative of the breadboard.

Result:

Whenever the LDR Module receives light it allows current to flow, and turns on the buzzer and the LED.
