Digital Communication System
• This project is one whereby we work as a team of 5 people to design a device where we can communicate with our lecturer from outside the staffs room without disturbing them. Outside the staffs room, there is a transceiver which is connected to a small LCD screen and camera. On the inside on the desk of lecturers, the receiver connected to the screen allowed the lecturers see and hear properly who they are communication with. The lecturers also have the option to activate the busy button whenever they are in the meeting and hence, from the outside the transceiver is locked for the busy option. The last option is being away whereby in the transceiver, you can send a message and they will receive it once they came back. The main device that helped us for this project is the raspberry pi 2.0 where we won the best creativity and the best project.
