Hi we made thi work but the control is in reverse. When it is darker the LED is off, when there is light the LED is on

camera thik karo vai

[@jackshanvenujan3115]

I used a line board instead for board.. It's not working...why..??? Always led is working. But. It's not controlled by the ldr

[@smartelectro7595]

Bro it's not difficult I expect that you consider the leg of transistor If it is not right the led glows continuously

[@smartelectro7595]

Bro just change the transistor instead you get a result also resistors It will increase your knowledge, about that circuit
