Problem
If you go to the toy market you will not find something related to us or our culture , how will the younger generation learn about us and be proud if they play with a toy that not related to us
Inspiration
I want to make a toy that reflects our culture because we have a rich history, so I choose tahteeb. Tahteeb (stick fighting) is an ancient Egyptian martial art that involves using long wooden sticks for combat or performance. It is both a traditional sport and a cultural dance practiced in Egypt, often during festivals and celebrations.

5- What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)
The Power Source I needed was a 5-volt power supply to power up the Arduino board and the components connected with it.
A 5V power source is used in this code because it is the standard operating voltage for most of the components, including the Arduino, servos, LCD, LEDs, and buzzer. Using 5V ensures compatibility, prevents damage to components, and simplifies the circuit design

6- Describe the code of your project. How did you program each function of the project?
I chose to split the circuit into two circuits, which I would eventually merge.
Circuit 1
Circuit 1
Servo Motor Control:
If swing1 button is pressed (digitalRead(swing1) == HIGH), the servo motor Myservo1 moves to 175 degrees.
If swing1 button is not pressed, the servo motor Myservo1 moves to 10 degrees.
Similarly, Myservo2 is controlled by the swing2 button.
Joystick Control for Stepper Motor:
The analog value from the joystick (analogRead(joystick)) is read and stored in val.
If val >= 600, the stepper motor moves one step in the forward direction (stepper.step(STEPS)).
If val <= 450, the stepper motor moves one step in the reverse direction (stepper.step(-STEPS)).
If val is between 450 and 600, the stepper motor stops by setting all control pins (IN1, IN2, IN3, IN4) to LOW.

Power Switch Check:
If the power switch is off (LOW), turn off all components (stepper motor, servos, LCD backlight, LEDs, buzzer).
If the power switch is on (HIGH), reattach servos, turn on the LCD backlight, and display the opening message if not already displayed.
Servo Control:
If Swing Button 1 is pressed (LOW), move Servo 1 to 175°; otherwise, move it to 10°.
If Swing Button 2 is pressed (LOW), move Servo 2 to 175°; otherwise, move it to 10°.
Joystick Control:
Read the joystick value from A0.
If the joystick is in the middle (450–550), stop the stepper motor.
If the joystick is moved to one side (>550), move the stepper motor clockwise.
If the joystick is moved to the other side (<450), move the stepper motor counterclockwise.
Score Tracking:
If Player 1 Increment Button (Pin 6) is pressed, increment Player 1's score, light up the Player 1 LED, and play a beep sound.
If Player 2 Increment Button (Pin 7) is pressed, increment Player 2's score, light up the Player 2 LED, and play a beep sound.
If either player reaches a score of 10, set gameOver to true, display the winner message, and play the win sound.

I got in trouble with stepper motor coding; it was not working at all, and the code was complicated, so Ahmed helped me a lot with this.
The servo didn't fit the arm, and I got lost with trying to solve this. Abdelrahman helped me to solve this.
I had a problem that the wiring is too much and the wiring is complicated in some areas and tangled, and I can't assemble the upper, so Fairda, Mayar, and my sister help me to sort out the wiring.

i shouldn't add adhesion because of that i had to sand the rail to make sure the gear fit
i shouldn't add adhesion because of that i had to sand the rail to make sure the gear fit
the servo didn't fit the arm ,so we use driller to make a hole in the arm and integrate the servo with screw
The support is too much and made my figure ugly. I solved this with sand and heating
The joints don't fit.
the joy stick didn't fit
Assembly
I had a problem that the wiring is too much and the wiring is complicated in some areas and tangled, and I can't assemble the upper, so Fairda, Mayar, and my sister help me to sort out the wiring.
I assembled the LCD in the wrong way, so I have to repeat the process.
The x slot is too thin, so it breaks when I assemble it.
When I assemble, I figure out that the rail is too long, and if they try to hit the head, it is impossible, so I solve this by making two rails for each player.
Coding
I use while to code the steeper and joystick. Because of that, the code stuck with it, so we changed it to if condition.
When we code the stepper, we have to make sure the inputs start with even the odd; in the final code, I miss this, so we think the stepper doesn't work and change it, but it is because of that!
I want to speed up the stepper motor, but it doesn't work. First, I try steps per revolution, but the speed is too slow. I try the accel, but it's the same. Finally, I get that if I reduce the speed and make the steps per revolution max, it will speed up, but when I integrate this with my code, it doesn't work, so I go back to steps per revolution = 200, and the rpm = 120.
When I was coding the counter score, I had two problems. I want the score to repeat when the game is ended, so I use the true/false method.
The functions were too much, and the code was too long and stuck with each other, so I used the void function method and put the buzzer and counting in the void function

I want to make a trigger point by sensor, but the pins are full.
If I have more time, I will add details to the figure to make it more traditional, make patterns inspired by our culture, and make a small message to make the children learn about the game.
