555 Timer IC as Monostable Multivibrator

With only minimal changes in wiring, the 555 timer discussed in previous article can be changed from a free-running oscillator (astable) into a switching circuit having one stable state and one quasistable state. The resulting monostable circuit is widely used in industry for many different timing applications. The normal mode …

Designing 555 Timer IC as an Astable Multivibrator

What is Timer IC 555? The 555 timer is an extremely versatile integrated circuit which can be used to build lots of different circuits. You can use the 555 effectively without understanding the function of each pin in detail. Frequently, the 555 is used in astable mode to generate a …
