The VF555/NE555 operates in three main modes: astable, monostable, and bistable. In the astable mode, it functions as an oscillator producing a continuous square wave output, making it ideal for clock pulses, flashing lights, and tone generation. In monostable mode, it generates a single pulse of a specified duration in response to an external trigger, useful for timers and pulse gene... https://vf555.work/
