555 timer is one of the most important and useful Integrated Circuit (IC) in the electronic circuit and it is often used in various kind of project. It can works in various function such as oscillator, pulse generation and time delay. It also can work as flip flop element. It is widely used due to low cost, stable and easy to use. It can operated either as a Monostable, Bistable or Astable Multivibrator to produce a variety of applications.
The shoe cabinet is a necessary to any place either home, office and many more. It is the place for storing multiple amount of shoes. Common type of shoe cabinet are made without the built in lamp inside causing it’s hard to find and look inside the cabinet when it is dark. Therefore, the shoe cabinet need to be modified and have the automatic light. The light will light up when the door is open and it will not light up when the cabinet door is closed. It will have time limitation. The 555 timer IC is one of the important component that will be used to create the circuit.
