555 Timer Astable mode, Lt spice simulation, and real-time testing  We know 555 timer has three operating modes called Astable mode, Monostable mode, and Bistable mode. Astable Mode : In Astable mode, 555 IC will act as an oscillator that generates a square wave  continuously .  The frequency of the wave can be adjusted by changing the values of two resistors and a capacitor connected to the chip.   LTspice circuit: Formulas: Calculations: Ton = 0.693(1k+100k)22uF =1.539ms Toff =0.693*100k*22uF =1.524ms T = Ton + Toff  = 0.693(1K+2*100k)22ufF=3.064ms  Frequency  = 1/T = 1.44/(1k+2*100k)22uF = 1/3.06ms =0.3263Hz Duty = 50.2% Simulation Results: Click here to download the Astable mode LTspice circuit Testing:
