Smart Feesha was inspired by the desire to simplify home automation and make it more accessible to everyone. The founders of the project (who is me :D)  recognized that many people are interested in making their homes smarter, but are deterred by the high cost of replacing existing devices with smart ones. I also saw that many people were overwhelmed by the complexity of setting up and managing various smart devices.

Therefore, the ideation for Smart Feesha was driven by the desire to make it accessible to everyone, while also being affordable, energy-efficient, and easy to use.

First, I defined 4 vars {

1. Relay: connected to pin 6;

2. IR: connected to pin 7;

3. Bluetooth: give him a '0' value;

4. Add a counter to use it in IR section;

 } 

Second, I setup 3 things:

1. The serial communication to connect between the Arduino and the Bluetooth and the android phone. The speed is 9600.

2. I defined the relay as an OUTPUT component.

3. I defined the IR as an INPUT component.

1. I used "while" as a serial from the Bluetooth equal (0) and I used serial.available to be ready to get the signal.

2. I used serial print to check the signal of the BT and write it. 

3. I used the "if" condition including the counter to open the relay when I take an action, like moving my hand around the ir and stating the value, and doesn't change it after moving it far away.  

4. Then, I rewrote the same code for turning off the relay and stating the new value as it is. 

The second part of the loop is the Bluetooth:

1. I let Arduino to read the signal from the BT module. 

2. Then I set charterer "a" which is the first button in the android app to turn on the relay, and "b" which is the second button to turn off. 

3. Also, I defined the charterer "o" to turn on when I say OPEN to the android phone and "z" to turn off when I say CLOSE.

4. At the end, I tell the Arduino to turn off the relay if it gets any other input or signal. 

5. I used the serial print to see the value of the IR and to show "Done BT" when it gets a signal from the Bluetooth.

After finalizing the IR code and the components worked, I wrote the code of the Bluetooth, after that the both didn't work. I tested the BT sperately and I found that it works. 

I tried to divide   the if condition to have to if conditions, for the BT and for the ir sperately. As a result, the BT worked only. I asked for a help from my instructor Menna and he adviced me to use "while" for the ir part and let BT part like it is "if". 

The IR and BT worked, but I found that I have to put my hand in front of the IR to let the device turn on and when I move my hand far away the device turned off. 

Menna advised me to add a counter to change and let the value like it is after taking the action (turn on or off), then when I change the value again by  moving my hand around the IR the counter will "state" the new value and make it permanent.
