Can you tell me in detail the function of lm555 (see attach file)?
Is it used to set the duration the buzzer will act?
Or to adjust the frequency of buzzer?
Still, it's said that the thyristor in this case is the same as a switch which means
not use the phase control function
Can you explain this to me ?
