Smart Home Circuit

The coding relied on defining the components of the smart home circuit, whether inputs or outputs, and the library for servo operation was used, as well as the library for the LCD, which is LiquidCrystal_I2C.h, and a variable named incoming Data was defined to store the value entered from the PCB Way remote control application. The if function and the if else function were used, so that this includes several cases, namely 1, 2, 3, 4, 7, or 8, in order to achieve the outputs that he set according to the Pseudo Code above.

I used all the outputs in the kit, and I was able to do that through downloading the Servo motor library, as well as downloading the LCD library, I also used the electrical resistors of 220 ohms, as well as 1 kilo ohm resistors, which helped me control the size of the voltage inside the circuit, as well as the use of the Motor Driver, which helped me control the DC motor(H-bridge), and the Delay helped me control the AC bulb, and through Arduino I downloaded the code for controlling the smart home circuit, and by completing the pairing process between the Bluetooth unit and ( PCB Way )software, this helped me control the smart home circuit.

At the first of the loop function the Arduino reads incoming data coming from Bluetooth, so if I choose button 1 then The LCD screen is controlled to write the following phrase “First Floor”, and the Seven Segment prints the number “1”, while the RGB LED lights up in white color.

So if I choose button 2,Through it, the LCD is turned off, the 7-segment is turned off, the RGB Led lighting color is converted to blue, the DC motor is turned on to move clockwise, and the AC bulb is turned on.

So if I choose button 3, Changing the RGB lighting to green, change the DC motor to counterclockwise, and turn off the AC bulb.

So if I choose button 4,Turning on the servo motor (90 Degree), which represents the opening of the gates at the time of danger, turn on the buzzer, turn on the LCD to print the phrase “Fire Alarm”, change the RGB LED to turn red, and turn off the DC motor.

So if I choose button 7, The LCD prints the phrase "Seventh Floor" and the AC Bulb is turned on, and the Servo motor returns to its original position ( Zero Degree) to close the gates due to the disappearance of the danger, and the Buzzer is turned off, and the RGB Led is also turned off.

So if I choose button 7,Turn off all of the above outputs.

The challenge is how to connect wires and 3 resistors of the type 1 kilo ohm between the TX pin in the Arduino board and the RX pin in the Bluetooth module, so as not to cause any damage to the Bluetooth module, which cannot bear the current value of 5 volts coming from the Arduino board. The picture in the PowerPoint slides in the tutorial was not clear enough, and accordingly, I sent this problem to the trouble shooting group on the Slack h application of the Maker Diploma batch, and through the help of a colleague, I was able to figure out the correct delivery method and it overcame me This challenge, and I made the connection according to the picture on the right, and thus I was able to complete the rest of the circuit.

I think that I have become able to deal with the Arduino-Uno control board in a much better way, and I have become able to use the pseudo code and coding to do programming, and I have also become able to integrate and make several outputs and Bluetooth Module to  work harmoniously together, and I have also become able to use Mobile app to have full remotely control on my Smart home Circuit, in addition to that I feel a great development in the ability to think logically based on problem-solving and creating Alternatives and thinking about the development of problems that may face the end user with the development of the largest number of solutions which will greatly reflect on facilitating work on my final graduation project.

I also gained logical thinking to visualize problems and develop the necessary solutions, as I was able to move between several modes, including, for example, but not limited to the "Safe Mode" and "Hazard Mode"

The most enjoyable thing for me is that I was able to Design, write programing code and have the full remotely control on my Smart Home Circuit, taking into account User Experience including simplicity, and aesthetic form, which is one of the most important customer requirements in products.
