The popular 555 from TI is an easy to use timer/oscillator with a friendly price tag.
These devices are precision timing circuits capable of producing accurate time delays or oscillation.
In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a-stable mode of operation, the frequency and duty cycle can be controlled, independently with two external resistors and a single external capacitor.
