It is a affordable, stable and user friendly IC in application such as monostable and bi stable. Here is the list of 40 555 timer circuits that can help you in understanding 555 timer functions.First five circuits explains about 555 timer and its different modes. List of Simple 555 Timer Circuits and ProjectsThe operation and output of the 555 timer monostable is exactly the same as that for the transistorised one we look at previously in the Monostable Multivibrators tutorial. The difference this time is that the two transistors have been replaced by the 555 timer device. Consider the 555 timer monostable circuit below. Monostable 555 Timer555 Timer 555 is an IC used to generate a clock. The two attributes of a clock are Frequency Duty cycle. Both of these can be changed using this IC, however the duty cycle is always <50%. There are two modes in which 555 can run. MONOSTABLE MODE As the name suggests; in this mode the output is stable in only one (mono) state i.e. off state If you want to learn more about the 555 timer, the book Timer, Op Amp, and Optoelectronic Circuits and Projects Book Vol. 1 By Forrest Mims is a great resource to have on your bench. The book has lots of information about the 555 timer, OpAmps, and other IC’s too. You can watch how each of the circuits in this tutorial work in this video:
