chmod +x Serial-Studio.AppImage

# Run the application
./Serial-Studio.AppImage

4.2 Setting Up Your First Project

  1. Connect Your Device: Plug in your hardware (e.g., an Arduino with sensors) via USB or connect to a network interface.
  2. Configure Data Input: Select the appropriate data source (e.g., COM port for serial).
  3. Design the Dashboard: Use the project editor to define widgets.
  4. Start Visualization: Stream data in real-time and monitor outputs.

4.3 Example: Visualizing Temperature Data from Arduino

Here’s a basic example of using Serial Studio with an Arduino to monitor temperature data.

Arduino Code

void setup() {
    Serial.begin(9600); // Initialize serial communication
}

void loop() {
    float temperature = analogRead(A0) * 0.488; // Example sensor calculation
    Serial.println(temperature);
    delay(1000); // Send data every second
}

Serial Studio Dashboard Configuration

widgets:
  - type: "gauge"
    name: "Temperature"
    min: 0
    max: 100
    unit: "°C"

Output Example

| Time (s) | Temperature (°C) | | | | | 0 | 25.5 | | 1 | 26.1 | | 2 | 25.8 |
