Can i uase 1k resistor instead of 2.7k ?

[@kenjisato8424]

If i want to use a 12v battery and led panel,i need to change the resistor??From 2.7k to 8.2k??

[@ABTabi]

You can try ,,,,,,,,,,, Thank you dear friend for interest ,,,,,,,,,,

[@aldo_domingo_2610]

Thanks for the video, help me.
Please, volts and watts of the led light?

[@ABTabi]

You welcome dear friend,,,,,,,, 4 volt and 10 watt led light,,,,,,,,,,, Thank's for interest,,,,,,,,

[@aldo_domingo_2610]

thank you

[@adrians.4311]

@@ABTabi so its consume 2,5 A.. well that's quite a lot and you can destroy that transistor

Please add solar panel for charging battery

[@ABTabi]

OK, dear friend ,,,,,,,,, i will make as soon as possible,,,,,,,, Thank you for interest,,,,,,,,,,,,

[@fireofenergy]

That's what I'm trying to figure out. Probably just put resistor on separate panel wire to base of PNP transistor. When dark, less voltage turns on base, turning on light. I believe the voltage of the base has to be more (sunlight on panel) in order to turn it off, just as the light dependent resistor.
And thanks to ABTabi for posting!

[@ardurinocreater8529]

Is it a amplifier

[@nsmadhvendra]

Sir, this circuit is working well, but its light does not turn off during the day, when the torch points to its ldr, then it's turn off
Please solv this problem.
Thank you and excellent video.

[@ABTabi]

Dear friend up the value of resistor ,,,,, Thank you dear friend for interest ,,,,,,

[@nsmadhvendra]

Sir the ldr is working well by increasing the value of the resistor to 10k, but the light becomes very low. The resistor is checked from 1k to 10k, as the value of the resistor increases, the light decreases.
Please provide a solution for this.
Thank you.
