555, Timer

The 555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays, or oscillation.

In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor.

For a stable operation as an oscillator, the free running frequency
