📚 Research
Interface programming allows users to interact with hardware systems through graphical or web-based applications. Interfaces can display sensor values, send commands, visualize data, or remotely control devices.
| Technology | Purpose |
|---|---|
| Serial Communication | Send and receive data directly from microcontrollers |
| Web Interface | Remote control and browser-based dashboards |
| Bluetooth | Wireless communication between devices |
| Processing / p5.js | Interactive graphics and visualization |
👥 Group Assignment
During the group assignment, we explored different interface development tools and tested communication methods between software applications and embedded systems.
- Compared web-based and desktop interfaces
- Tested serial communication workflows
- Explored wireless control systems
- Reviewed debugging and monitoring tools
👤 Individual Assignment
For my individual assignment, I created an application interface that communicates with my embedded system. The application was designed to visualize data and send commands to the microcontroller.
- Designed interface layout and controls
- Implemented communication with ESP32 / Arduino
- Displayed live sensor or device data
- Added controls for interaction and testing
⚙️ Workflow
- Plan interface structure and communication method
- Develop application layout and functionality
- Configure serial or wireless communication
- Connect application to embedded system
- Test data transfer and controls
- Debug and optimize performance
🔌 Communication & Integration
The application communicates with the microcontroller using serial or wireless communication. Commands and sensor data are exchanged in real time.
// Example JavaScript serial communication
const port = await navigator.serial.requestPort();
await port.open({ baudRate: 115200 });
const writer = port.writable.getWriter();
const data = new TextEncoder().encode("LED_ON\n");
await writer.write(data);
writer.releaseLock();
🧪 Testing & Validation
| Test | Expected Result | Status |
|---|---|---|
| Device Connection | Application connects successfully | Success |
| Data Transmission | Commands are sent correctly | Success |
| Data Reception | Sensor values update live | Replace with your result |
