According to the the schematic diagram that was appeared in the video i draw it in proteus app and used a Torch LDR when i make the torch near to the LDR the LED-Blue glows and if i get it way the led extinguished so i think it becomes light sensor not darkness sensor what should i do?

To make it a light sensor, should we just swap the position of the LDR and the 2.2K resistor?
Yes you need to balance the resistance of LDR and the external resistance
hey bro i liked the project.. its better than others
Thanks
Wow I wonder how the other projects will be like if this is the best one sheeesh
What resistor i should use with 5v battery. Thank you for reply
No need to change any resistance value
Hi, Can i use IC741? thanks for reply
This is used for another circuit...circuit diagram will be changed.. you cannot use IC741 in this provided circuit diagram.
Whats the value of ldr
Thank you for the idea, very useful for me
Welcome.. and keep sharing
@@EProjectbox
Very usefull sharing.
Ist it enough to make sensitivity adjustable by replace R1 with potentio?
thank-you so much
Hi. I wanna ask you, why the led keeps light up eventhough in the dark? I exactly follow your cct.
It is darkness sensor..the LED glew till untill your room get bright..
Can i use LMC555 instead of NE555?
Yes you can use

Depending up on the ldr resistance we should increase or decrease the balancing resistance (R1) value
As i know, dark or light sensor depend on position of LDR n R1.
Just exchange position of LDR n R1, it will become "dark / light changeable".

Yes
How are you able to read the breadboard so easily?.
With practice
What resistor i should ude with 12v ?
You can use 2.2k
@@EProjectbox thank you!
My led is glowing without darkness aslo...wht to do?
Set the value of regulator registor
I need some explanation on this
bro i need circuit diagram for 12v output and 12v input ! help me
Use a voltage step up circut in output and this circuit is capable of 12 v input
Voltage step up circuit:
th-cam.com/video/kQbTqN9hXPg/w-d-xo.html
No output
Didnt work for me
Recheck the circuit diagram
How it's work in theory
