Motivation
1. Solve some problems in education like projector.
2. Some times, people need to display content on screen rather than laptops, mobiles.
Project Idea 1. External, remotely-controlled device,
compatible with the any display screen with HDMI interface.
2. Used to utilize the available display screens to access many websites and applications making that screen interacting with the user instead of being just used for displaying.
3. The system can be controlled using icons on the screen as well as remote control.
Objectives
1- To design a smart TV system that is able to provide the Internet access to a TV screen.
2- To implement and easy to use system.3- To produce the smart TV system as a final
product.
Objectives (cont.)
4- To provide the customers a product that is less expensive than other products.

Raspberry pi
Hardware design
Connect IR receiver with GPIO
Connect IR receiver with GPIO
send the signal with use IR remote to the IR receiver
the IR receiver it receive the signal and
send it to the microcontroller
the system will open (display the icons in
the screen)
you can choose any icon and open
it with remote
the signal will return to the microcontroller and choose the IP
address
the router will recognize the IP
address to determine the position
the screen will show the result and we can access to the internet
sequence diagram
• Python is a high level interpreted ,interactive and object oriented scripting language .
• Python was designed to be highly readable which uses English keywords frequently where as other language use punctuation .
Python's feature
• Easy-to-learn. • Easy-to-read. • Easy-to-maintain. • A broad standard library.
How to write the code? • Write a code of the graphical interface .• Write a code to open the web browser .• Write a code to display the video that store in
raspberry pi or external device (USB).• Write a code of IR remote .
Implementation of the project
Challenges1- The programming language because we learn this language without any one learn
me .2- To read the codes in many remote
control .3- To appear the graphical interface in
raspberry pi .4- The availability of components in
.the market
5- To control of the video .
6- To control of the system by using IR remote .
Challenges (cont.)
Future work 1- Add application in your mobile to control the system .2- Add more web-site .3- Control the system with using the voice or use gestures by using camera .4- Add another application not just to browse the internet .
