Project Scope
This project is an interactive Morse Code Translator that:
- Lets users input Morse Code using push buttons.
- Outputs the corresponding text and plays light and sound signals.
- Utilises servo motors to visually represent letters.
The project combines historical inspiration with modern engineering to create a functional and engaging device.
My Role
As the sole developer of this project, I was responsible for conceptualising, designing, and building the Morse Code Translator. I handled all aspects of the project, including hardware assembly, code development, and debugging. Additionally, I created detailed sketches and a flowchart to visualise the system’s logic and design.
Work Process
Components Used
The Morse Code Translator was built using the following components:
- 5 resistors
- 4 push buttons
- 7 servo motors
- 1 LED
- 1 buzzer
- 1 breadboard
- 1 Arduino
- Various connecting wires

Outcome Achieved
After extensive testing and iterations, the Morse Code Translator successfully:
- Converts user input into Morse Code or text.
- Uses servo motors to visually represent letters.
- Provides accurate light and sound feedback.
Operation
- Short click: Represents a dot (

Challenges Faced
- Troubleshooting the circuit:
- Initial wiring issues caused incorrect signals.
- Debugging code:
- Logic errors in Python led to unexpected results.
- Framework unfamiliarity:
- Learning the AAD framework was challenging but rewarding.
- Servo motor calibration:
- Fine-tuning was crucial for accurate letter representation.
