This is a 555 based Oscillator simulation, where the 555 timer IC is operating in astable mode to continuously generate clock pulses. With the help of two resistors (1 kΩ and 2.19 kΩ) and a capacitor (1 µF), the charging and discharging cycle creates a repetitive square wave output. The waveform observed on the oscilloscope has a frequency of about 255 Hz and an amplitude of nearly 3.5V. Such 555-based oscillators are widely used in timing circuits, waveform generators, LED flashers, and tone ge
