The 555 multvibrator chip can be operated in monostable mode (one pulse at a time) Or in Astable mode (retriggers itself in freerun mode) This IC puts out a nice clean square wave . The output of this chip is capable of driving a small speaker.

What is the mode of operation of IC555 timer in Automatic street light controller?
it is astable operation to produce clock pulses for the counter
Astable multivibrator can be used as?
An astable multivibrator such as simple 555 timer circuit can be used as a clock source, turning LEDs on/off at timed intervals, or at frequencies between 20hz-20khz to generate sound audible to humans
What Are The Applications of IC555?
An IC 555 is used as as a timer, as an astable and monostable multivibrator and as a square wave generator.
Why no triggering is used for astable multivibrator?
No triggering is used on an astable multivibrator because it can cause it to become unstable.
Why do you use npn transistors in an astable multivibrator?
You can create an astable multivibrator with PNP, NPN, FETs, or even with NOR gates, NAND gates, or NOT gates. In fact the escapement movement in a mechanical watch is a species of astable multivibrator.
How many state in astable multivibrator has?
no stablestate
How DC is converted to square pulse?
The easiest way to convert the DC Voltage to pulse is simple astable multivibrator. This can be achieved either directly by astable multivibrator ic's or using normal transistor and resistor combination circuits or by using 555 as astable multivibrator.
Why astable multivibrator called free running oscillator?
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
What is astable?
An astable multivibrator [also known as an oscillator] is a circuit built so that it does not come to rest in one single state but switches between them continuously.
What is the use of a astable multivibrator?
1. It is used for the performance of many digital operations such as counting and storing binary information. 2. It is also used in the generation and processing of pulse-type waveforms.An astable multivibrator [also known as an oscillator] is a circuit built so that it does not come to rest in one single state but switches between them continuously.
What is astable multivibrators?
An astable multivibrator [also known as an oscillator] is a circuit built so that it does not come to rest in one single state but switches between them continuously.
Where can you find a 555 timer?
in multivibrator circuits.
