Li-Fi or Light fidelity is a wireless Communication Technology that uses the

light to transmit data and information among different devices. Li-Fi can send

the data at a very high speed

Project Description:

- You are required to build a small prototype (Sender + Receiver) that

can be put in our homes for hazards detection. it works as below:

1- The sender platform tiva c (TM4C123GH6PM) is connected to three sensors

(Fume Sensor, Ultrasonic Sensor, And Magnetic Sensor).

2- If sensors detect any danger (ex: fire sensed by fume sensor , Door is opened sensed by magnetic sensor, or intrusion sensed and distance is calculated by ultrasonic distance). Tiva c built in leds will light on and off to send Data to the receiver board which will be an arduino,

to turn on alarms represented in a flashing Lamp, buzzer, and a

LCD that displays a sentence related to the detected event (ex:

Fire is reported). An LDR will be used on the arduino to receive data from tiva c

-Bluetooth to a mobile phone (app inventor is an easy option)

with the same sentence as the LCD.

3- The system has 2 pushbuttons for the start/stop operations. it can be

closed at any time.

4- If any alarm fires, the sounds continue until a mute pushbutton is

pressed.

5- When the mute pushbutton is pressed, all alarms will be turned off after

5 seconds, but the system is still powered on.

-so the tiva c will have , 3 sensors and bluetooth module.

-arduino will have the LDR to receive data from tiva c and LCD and buzzer and lamp

-i will be using the tivaware library
