The SE555 is a precision timing circuit capable of producing accurate time delays or oscillation. In the time-delay
or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor
network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two
external resistors and a single external capacitor. …
