The resistance of ldr increases in darkness and reduces in presence of light.
C1 together with the inductor l0 and c2 make up a pie filter network for cacelling emi disturbenaces.
This circuit is same as a dark detector or light.
The circuit diagram for leds in parallel connection is shown in the following image.

The input mains 220v or 120v ac is half wave repaired by d1 and c1.
Hopefully those looking for practical information on electrical circuits and wiring led components found this guide first.
In this project we have used an ldr light dependent resistor which is responsible for detecting light and darkness.
But in this project i have used ldr light dependent resistor.

It s likely though you ve already read the wikipedia page about series and parallel circuits here maybe a few other google search results on the subject and are still unclear or wanting more specific information as it pertains to leds.
Automatic street lights turn themself on and off automatically by sensing intensity of light with the help of lights sensors.
Note that the concealed photo switch is intended to be mounted on the lamppost.
In this circuit we will try to connect three 5mm white leds in parallel and light them up using a 12v supply.
There are many lights sensors available in market.
