For this project, we use 2 IC such as NE 555 Timer and inverter 7404. The NE555 IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator
applications. The NE555 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.. An inverter 7404 circuit outputs a voltage representing the opposite logic-level to its input. A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a low-power signal or where several circuits must be controlled by one signal.
