Windows GUI Development for Arduino Control

I'm looking for a skilled developer to create a Windows-compatible GUI for a project. The software should be developed in Java or C++ using Processing 4.3. The interface will contain approximately 5-6 options and will feature a real-time line graph.

Key elements of the project include:
- Designing a user-friendly GUI with 5-6 options
- Implementing a real-time line graph
- Ensuring the GUI is compatible with Windows
- Programming the GUI to send commands to an Arduino-based microcontroller

Ideal candidates will have prior experience in:
- Java or C++ development, particularly with Processing 4.3
- Creating GUIs for Windows
- Microcontroller programming, specifically with Arduino
- Real-time data visualisation

The successful freelancer will have a keen understanding of these requirements and be able to deliver a high-quality, functional GUI.
