Wi-Fi is a popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.

Many devices can use Wi-Fi, e.g., personal computers, video-game consoles, smart phones, some digital cameras, tablet computers and digital audio players.

These can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater range outdoors.

It eliminates the requirement of a wired connection by providing a wireless path

Block Diagram
VNC Server Setup
This will be the transmitter(device /system),which will be transmitting the photocopy of the screen from system to the client (i.e. raspberry pi) frame by frame through RFB protocols .

The client receives the frames from the transmitter
and sends it to the projector via VGA connection.

Further the projector will display the contents received
from the client which will be a photocopy of the system/
device.

Future Progress Of The Project
On the present transmission of the frames is by internet and not through, it is because to verify that the frames are been received properly to the client and displayed on the screen.

Later the same protocol will modified for Wi-Fi connection.

This will be the further and final stage of our project.

Projector Screen
Problems with HDMI ports not connecting to projectors.

Presentations to be given without laptops.
