555-timer IC (integrated circuit) is used to generate an accurate delay and oscillations in electronics. It works either in monostable, bistable, and astable mode. The IC gets its name because of the three 5Kohm resistors present in the circuit. The basic constructional features include a voltage divider network, comparators, a flip-flop, transistors, and an inverter. … Read more
