IDEA & INSPIRATION :
project is an automated card shuffler and dealer, designed to shuffle and distribute playing cards. The goal is to make card games faster, and more enjoyable by removing the hassle of manual shuffling.
WHY THIS PROJECT :
I love card games, especially Uno, regular playing cards, and سكروو I thought it would be fun to build a device that could shuffle cards It felt like a cool and practical project that could add a unique touch to our game nights.
PERSONAL TOUCH :
I wanted the project to reflect a part of my personality, so I thought about adding a fun theme. After some brainstorming and research, I found no better than the panda🐼🥰 a calm, lovable, and playful animal

Focused on ensuring the correct dimensions to fit the cards properly.
Designed the structure to be stable and easy to load.
Focused on designing the pushing wheels for proper friction and the card passage for smooth movement.
Imported the motor and IR sensor models and designed mounts to secure them in place.
2. Second part of the design, I created the dealing
Designed the card holder to securely stack the cards before dealing.
Created a long wheel to push the cards one by one.
Added a mounting space for the motor to drive the wheel smoothly.
Ensured proper alignment so the cards are dealt correctly.
3. Third part of the design, PANDA🐼
Designed the face, hands, and legs to complete the panda shape.
Created slots in each part to ensure they fit securely with the other components.
4. Fourth part of the design, Base of component
Designed the base structure by creating the top, bottom, and side panels.
Imported the components (Breadboard, 2 H-bridge, LCD, and Arduino).
Created mounting points to securely fix all components in place.
Added a small panda SVG engraving on the front panel for a personalized touch.
5. Fifth part of the design, Wheels
Shuffling Wheel: Created a wheel with enough grip to push the cards smoothly.
Dealing Wheel: Designed a longer wheel to reach and push the cards out.

Step 1: Shuffle part code
In week 6 assignment, the core functionality of the shuffling mechanism was implemented. The code was initially developed using code blocks, and later modifications were made to enhance its performance.
Key modifications:
Added a second motor for improved card shuffling.
Integrated a switch to control the system.
Replaced the ultrasonic sensor with an IR sensor for more precise card detection.
uses if, while, and for loops to control the process.
The switch (switchPin) is checked to start or stop the operation.
The IR sensors detect card presence before starting the motors.
Motors run until the sensors confirm the process is complete.
INPUT_PULLUP is used for the switch to keep it HIGH by default, preventing false triggers.
If Condition: Button Press
If buttonPin is LOW (button is pressed), the dealer motor turns on by setting dealer_motor1 to HIGH and dealer_motor2 to LOW.
Else Condition: Button Release
If the button is released, both motor pins are set to LOW, stopping the dealer motor.
If Condition: Switch is HIGH
If switchPin is HIGH, the function exits (return), stopping execution and turning off everything.
Step 2: Dealer part code
In week 6 assignment, the core functionality of the shuffling mechanism was implemented. The code was initially developed using code blocks, and later modifications were made to enhance its performance.
Key modifications:
Added a second motor for improved card shuffling.
Integrated a switch to control the system.
Replaced the ultrasonic sensor with an IR sensor for more precise card detection.
Step 3: LCD messages
Library Installation & Integration
Installed the required LiquidCrystal_I2C library.
Checked its example codes inside the Arduino IDE.
Integrated it into the main project.
Customization & Modification
Adjusted the messages to fit the project's flow.
Cleared the display (lcd.clear()) before printing new messages.
Used lcd.setCursor() to position text correctly.
Ensured updates are displayed at the right moments in the workflow.
Step 4: Full code
Defined variables : Assigned pins for motors, sensors, switch, and button.
Initialized components : Set pin modes and initialized LCD.

9- When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?
First challenge I faced was in the design
I planned to use the wheels that came with the motor. However, after cutting the part where the wheels would be placed, I realized they were too large and became an obstacle.
The solution was to use 3D-printed wheels instead. I designed them myself, which successfully solved the problem.
Solution
Second challenge
was with one of the sensors, which most likely received a higher voltage than it could handle, causing it to malfunction.
The solution was to buy a new sensor and use a voltage regulator to ensure it receives a stable 5V supply.

Solution
Last challenge
The last challenge was that multiple cards were coming out at once from the exit slot in dealing.
The solution was to add a thin strip at the top of the slot, reducing the opening by about 1mm. This improved the process, but sometimes the card exits more slowly.
