Continuing on from our first look at the operation of the 555 timer, this second tutorial about the 555 Timer looks at some practical uses and circuits we

The 555 Timer IC can be connected either in its Monostable mode thereby producing a precision timer of a fixed time duration, or in its Bistable mode

We have seen that Multivibrators and CMOS Oscillators can be easily constructed from discrete components to produce relaxation oscillators for generating basic square wave output

We have seen in the last few tutorials that the 555 Timer can be configured with externally connected components as multivibrators, oscillators and timers, with timing intervals

In the previous tutorials we have looked in detail at the three different types of basic transistor multivibrator circuits that can be used as relaxation

Regenerative switching circuits such as Astable Multivibrators are the most commonly used type of relaxation oscillator because not only are they simple, reliable and ease of construction

The Bistable Multivibrator is another type of two state device similar to the Monostable Multivibrator we looked at in the previous tutorial but the difference this time

Multivibrators produce an output wave shape resembling that of a symmetrical or asymmetrical square wave and as such are the most commonly used of all

In the Oscillators  tutorials we saw that an oscillator is an electronic circuit used to generate a continuous output signal. Generally this output signal is in the
