Hello,
Could anyone please tell me what is the problem in the following circuit? Thank you.
There's nothing *wrong* with it, its just missing some fairly important stuff, and is *STUPID* unless LED1 has Vf>4V or min. If for acceptable brightness >25mA!
Thank you for your answer. I mean what could be a problem with that?
Well you've just deleted the circuit diagram, so I'm working from memory.
If you want it to be buildable, specify component values.
If the LEDs power requirements are significantly under the limits I suggested, why not power it direct from the ATtiny I/O pin (with an appropriate series resistor)?
N.B. No-one here is likely to provide full solutions for anything that appears to be a student exercise. You have to do the course work for yourself to learn the skills you will need once qualified and employed. No-one wants to work with colleagues who have the paper certificate but don't have the knowledge or ability to do the job. If you are *NOT* a student undertaking a formal course of instruction, and didn't take it down because you needed to remove it before your lecturer saw it or your college's anti-plagiarism software picked it up. However, in general we are quite happy to guide you towards solving it for yourself, or even check your answers if you don't conceal the fact its a student exercise. I apologize in advance for assuming you are a student, but only *IF* you can provide any evidence of your non-student status!

There are no components, connections, anything.
IIRC it was an ATtiny 10, with a +5V supply and a pullup resistor on /Reset, with PB0 driving the gate of a BSS123 N-MOSFET, with a LED + series resistor between its drain and +12V. No other components or component values were shown.
