Design a system using Arduino microcontroller to com between two machines $200$m apart in an industrial factory. Machine $1$ can sent a command to turn ON$/$OFF the second machine. Also it can ask for its status $($ON$/$OFF$)$ and can ask about the production count. Machine two when asked from machine one $($production count$)$ sends a response back to machine $1$ with a variable contains the number of items it produced up to that moment it does not lose the count when it turned off. $(5$ pts$)$ Draw the block diagram of the system.
