Prepare a user$-$friendly system design that can handle some unexpected events, including:$*$ the selection and justification of suitable input and output devices$*$ a description of the system design covering input and output devices and microcontroller connectionsa plan for the program structure detailing key system operations.Using brief below $1$ A call button is pressed next to the door at Level $0$ or Level $1\mathrm{.}2$ If the goods lift is at the other level to the user, it will move to the level called and stop$\mathrm{.}3$ After a short time delay, the door can be manually opened to allow the user to enter and the goods to be placed inside$\mathrm{.}4$ When inside the goods lift, the user must manually close the door$\mathrm{.}5$ The user must press a select button for Level $0$ or Level $1\mathrm{.}6$ The goods lift will start to move to the other level after a short time delay$\mathrm{.}7$ The movement of the goods lift to the other level takes $10$ seconds$\mathrm{.}1.$ The goods lift stops$\mathrm{.}2.$ After a short time delay, the door can be manually opened by the user so they can exit and remove the goods$\mathrm{.}10$ After they exit, the door must be manually closed by the user$\mathrm{.}11.$ The process repeats from $1.$The client has not stated that the DC electric motor needs to change direction to move the goods lift between levels, as this could be achieved in other ways.To control the goods lift, One$90$ Lift Services has requested a prototype control system that will, as a minimum:$*$ indicate that the call button has been pressed on either level$*$ indicate when the door to the goods lift can be opened$*$ indicate the level that has been selected when inside the goods lift$*$ control a DC electric motor to move the goods lift to the other level.
