Some of us need, after a long and hard day’s work, to sleep quietly and do a few meditation exercises before bed to enjoy a quiet and comfortable sleep instead of browsing the mobile and based on my interest in modern designs of Islamic art, I wanted to use that to make a smart bedside lamp...
I was excited about this idea for two reasons, the first because I actually suffer from this problem, as my workdays are usually hard and I need something to help me sleep peacefully and practice meditation, and the second is because I want to use Islamic motifs in the manufacture of a smart device to make new designs based on our oriental culture and designs
My main source of inspiration in terms of the idea was our old use of the traditional kerosene lamp and its flame continued until the morning. As for the design idea, it was inspired by the designs of Moroccan and Mamluk lanterns, and in terms of technology, I searched and found similar products on YouTube, and the “Wanasah” project was one of the inspiring projects...
DoDe. lamp, which would be sensitive for the level of light, where when the level of light is low, it starts to work automatically at a low brightness until it reaches the appropriate level for sleeping at night and also rotates to spread the ornaments formed on it around in an aesthetic way, and after 15 minutes it will turn off automatically. The user can change the intensity of light and changing the timer setting, also can pause it.

I used the Fusion 360 to design from scratch on sketches and saved it as a DXF file to develop it on Corel Draw & Laserwork software .and the project was divided into four parts...
For the first part of the geometry drawing, I drew it manually, then I copied the steps to Fusion 360, then after completion, I transferred the sketch to a new project to make offset and trim, then I extracted as DXF to develop it and assemble with shape faces sketches on Corel Draw software.
Note: Fusion is not suitable for this type of design. It is better to use AutoCAD and then import the DXF files to Fusion.
In the second part, I drew the parts of the lamp, I drew the upper and lower part and the connections, then I made sure that the drawing was valid by extruding and assembly options.
In the third part, I drew the Components enclosure and import the components from GRABCAD to assemble it and make the final sketches with screws holes.
The cardboard prototype helped me a lot in transferring the measurements and ascertaining the locations of the components on the enclosure.
In the last part, I made the coupling part that connects the stepper motor with the top of the upper part of the lamp.
After Assembly and adding the appearance.

This circuit contains a stepper motor, an LED strip, and an LDR light sensor, and these are the main components to perform the lamp's function. Once the light sensor senses a low light intensity, the motor starts to move and the LED strip lights up gradually.
it will be turned off automatically after 15 minutes, but the user can change the time and set a new one using the rotary encoder, also can restart the lamp using it.
the user can change the intensity of light using the potentiometer, and pause the lamp using the push button, and the function of the LCD Screen is to display the welcome message and timer setting and pause message.
The input components:
LDR Sensor: to sens the intensity of light, if it lows the lamp turns on
1k Potentiometer: to change the intensity of light.
Rotary Encoder: to change and set the timer, and restart the lamp after time out.
Push Button: to pause the lamp.
On/off switch: to turn on the circuit.
The output components:
5v stepper motor: to rotate the dodecahedron cover.
LED Strip: the main lighting unit.
LCD with I2C module: to display the welcome message and timer settings, and pause message.
Other components:
Arduino Uno Board: for controlling the electronic circuit.
Motor Driver "ULN2003 Driver Board": to drive the motor.
L298 Module (H-Bridge): To convert the value of the voltage entering the circuit from 12V or 9V to 5V to be suitable for the Arduino board as well as the stepper motor.
Breadboard: to connect the GND and VCC wires.
power jack female: to receive power from the electrical source.

6- Describe the code of your project. How did you program each function of the project?
It is not easy for me to write the code yet, so I divided the code into several functions and programmed each function separately, and then combine them with the help of instructors ...
I installed and included the libraries I'll need in this code:
AccelStepper: for Motor.
LiquidCrystal_I2C: for LCD Screen.
I used a ready-made code for the stepper motor just changing the pins number and the values to be suitable for this project...
I used a ready-made code for the rotary encoder and made some changes by adding counter and interval while using millis() function...
I revised the code of week 8 to define and write the right code for LCD Screen...
I made the main condition of this code depending on the code I write it before at weeks 6 and 7 using map() to change the value of the intensity of light.
----
boolean: A boolean holds one of two values, true or false. (Each boolean variable occupies one byte of memory.)
it helped me make the soft-start in the void loop without needing to make it in the void setup, also I used it to make the pause condition and timer.
unsigned long: Unsigned long variables are extended size variables for number storage, and store 32 bits (4 bytes).
I used it to save the interval of the timer.
millis(): Returns the number of milliseconds passed since the Arduino board began running the current program.
I used it to count the time more accurately than the delay() function, cause the last one had more bugs and errors.
I reviewed the entire code with Muhammad Askar to ensure its effectiveness, errors were corrected, the numbers were reviewed, and we reached a good result.

The second challenge was while writing and trying the code, after writing the code for the LED strip and trying it successfully, I started writing the code for the motor, and the motor was not responding to the signal, I thought for the last moment that the problem was in the motor, and I tried a new motor, but it did not help, And by trying a different Arduino board, it turned out that the Arduino board does not work efficiently with all the components and I had to replace it with a new one
-------------------------------------
As for the biggest challenge, it was how to assemble the lamp cover at right angles, due to the difficulty of assembling the dodecahedron shape, whether the assembly was on the Fusion 360 or in reality, I searched on the 3axis website for similar projects and relied on a ready-made design to transfer the sizes from it and adapt it to fit My design, but the result was bad due to the designer’s error in calculating the angle, then I started searching through YouTube on how to draw the dodecahedron shape. I found several videos and started experimenting with drawing them to find out the appropriate angles, then I redrew the drawing again according to the angles deduced from watching the videos and calculating them from cardboard using Aristotle’s triangle and Some traditional methods. Finally, I drew it carefully and succeeded in assembling the shape.
-------------------------------------
Another challenge we faced during connecting the potentiometer, which is the instability of the jumper wire with it, and it had to be soldered, Ahmed Abdel Nasser helped me with that
The first challenge I faced was changing the two main components in the project and replacing them with other components with lower volts and DC power to suit the Arduino and to avoid the danger of high voltage electricity.
-------------------------------------
Before showing the recent video library, I did not know how to install the lamp cover on the motor and I thought of many complex solutions that contain a lot of work with gears and mechanisms that might fail because I could not design them well or calculate them accurately. Amani and Michael helped me with the idea of coupling and I have already done.

I would add some aesthetic touches to the shape to display the lighting better, such as lining the interior with a material such as acrylic or soft white fabric.
And I was going to add a Bluetooth module to connect the control unit to the mobile to give another feature to the user so that he can connect the timer with the mobile alarm...
