Hello.
My name is Muhammad, 14-year-old boy from AU.
I am a beginner hobbist with an interest in electronic circuits.
A few months ago, I got an electronic circuit diagram from radio-flier.com.
https://www.electro-tech-online.com/custompdfs/2008/03/LZ3W.pdf
That is a solar-poweed night light circuit schemetic without a light sensor like CDS.
If that is correct, the LED have to turne on at night and off at sunlight.
But my result was unsuccessful because the LED worked directly opposite to its originally design.
I applied all components in the same way only besides Q2(I used 2N3904)
I tried several times but the results were same.
I don't know what mistakes are there.
What's worng?
Anyone help me?.
