Bhai Sab 100k ohm resistor use karo nahi toh output nahi nillega

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 4 года назад

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

@smartelectro7595 4 года назад

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