This video explains the 555 timer in its monostable mode, covering how the internal components—comparators, flip-flop, and discharge transistor—work together. Using animated graphics and live demonstrations, I guide you through the entire monostable cycle, from triggering the circuit to capacitor discharge and resetting the output.
If you are interested in seeing my previous video (“It’s Not a Timer”) which goes into more depth about the 555’s internal building blocks and provides details of the Astable circuit arrangement, click on this link below:-

For a better understanding of Capacitor Charge and Discharge timings, when coupled with a resistor, see my “Capacitor Timings” video at the link below:-
