Microprocessor Based Systems - Design Hotel-room’s door control board -- 2

Design Hotel-room’s door control board. The main building block is TivaC board (Simulated at keil not real). The designed control board shall lock and unlock a solenoid lock. The control board gets its inputs from the hotel receptionist’s PC through (UART) or from the guest using keypad. Mode of operations: 1. Setup a. Store the room no in the control board (To be done via UART connection with PC) 2. Status of the room (To be done via UART connection with PC) a. Free b. Occupied c. Room Cleaning 3. Set password (To be done via UART connection with PC) a. Store 4 digit password by the receptionist’s PC while check-in 4. Open the door using the password by the guest using the password. a. Check the password and unlock the solenoid The design document shall contain:  The bill of materials.  Detailed circuit diagrams including the signal conditioning circuits and interfaces  The C code developed in your design. Complied and Simulated or just compiled.
