LM555 is a timer it can be used for many applications not only oscillators. the timing can be setup from microseconds to hours by the right choice of external passive components. Timing is set precisely by laser controlling a voltage divider as .639. So while the chip is precise the external components are not. but that is used to begin a design.

What is a 555 IC and what is its working logic?
The 555 timer IC is an integrated circuit ,that is used mainly in a variety of timer, pulse generation, and oscillator applications. It can be used to provide time delays.
What does a 555timer do?
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator , and as a flip-flop element . Derivatives provide up to four timing circuits in one package.
Which oscillator circuit uses a tapped coil in the tuned circuit?
Several oscillator designs use a tapped coil in the tuned circuit. The most common is the Hartley oscillator.
Do 555 timer used to set time?
No. It's an oscillator.
What is 555 Timer IC?
The 555 timer is a device that allows you to provide a timing signal to a controlled circuit. You provide an RC or other type of tunable circuit. Once triggered, the 555 will provide an output of a set duration. Depending on configuration, it can also be used as an oscillator, or as a flip flop.
What the major components of a colpitts oscillator?
1.CE amplifier circuit 2.LC oscillator circuit
What is the roles of 555 timer circuit?
The 555 timer IC is a device that can create various kinds of time delays in a circuit. It uses a threshold pin that is typically connected to an RC circuit. Depending on how it is connected, it can operate in one shot mode (monostable), astable mode (retriggerable), or schmitt trigger mode.
What is blocking oscillator?
The oscillator which is blocked by using transformer is called a blocking oscillator. Generally, the primary is given to the base and secondary is given to the collector of the transistor used in the oscillator circuit.
What what is an oscillator?
a circuit that produces a continuously oscillating signal.
What is the purpose of an oscillator crystal?
"A circuit within a computer that creates a series of pulses that pace the computer's electronic system. The oscillator clock synchronizes, paces and coordinates the operations of the computer's circuit." -- webopedia
What is a local oscillation?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)
