Virtual Window Remote Control

The Remote Control component of the Virtual Window System is a hardware-based device designed to provide intuitive, tactile control over the virtual window experience.
This ESP32-powered device connects via Bluetooth to the Virtual Window system, allowing users to adjust settings like brightness, volume, and ambient music directly from their workspace.

Hardware Components

• ESP32-S3-Touch-LCD-4.3: Development board with integrated LCD touchscreen (https://www.waveshare.net/wiki/ESP32-S3-Touch-LCD-4.3)
• 18650 Battery: Rechargeable lithium-ion battery for portable operation
• Battry box with PH2.0 Connector: For reliable battery connections
• Power Switch: To control power on/off

Software Stack

• Arduino IDE: For firmware development and deployment
• LVGL (Light and Versatile Graphics Library): For creating the touchscreen interface

Usage

1. Power On: Use the physical switch to activate the device
2. Pairing: Connect via Bluetooth using the bluetooth button in the projector app. Choose Virtual_Window_Control in the pairing panel.
3. Adjust Settings: Use touch screen to modify brightness, volume, and music selection

Here is a well-structured Deployment section for your README.md file, tailored to guide users through the deployment process of your Remote Control project using the ESP32-S3-Touch-LCD-4.3 board:

⚙️ Step 2: Configure Board Settings

1. Go to Tools > Board > ESP32 Arduino.
2. Select your board: ESP32-S3-Touch-LCD-4.3 or ESP32S3 Dev Module (or equivalent).
3. Set the following options in the Tools menu:

Option	Value
Upload Mode	UART0
PSRAM	OPI PSRAM
Flash Mode	QIO
Flash Frequency	80MHz
Flash Size	8MB
Partition Scheme	8MB with spiffs

🔌 Step 3: Connect the Device

1. Connect the ESP32-S3-Touch-LCD-4.3 to your computer using a USB Type-C cable.
2. Ensure the board is recognized by your system:
   • Check the Tools > Port menu in Arduino IDE to confirm the correct COM port is selected.

---

📤 Step 4: Compile and Upload the Project

1. Open the project .ino file in Arduino IDE.
2. Review and adjust any configuration parameters if needed (e.g., BLE service UUIDs, default settings).
3. Click the Verify button (✔️) to compile the code.
4. Once compilation is successful, click the Upload button (➡️) to flash the firmware onto the device.

⏱️ The upload may take a minute. Once complete, the device will automatically reset and start running the firmware.

🧪 Step 5: Test the Remote Control

1. Power on the device (ensure the power switch is engaged).
2. The screen should display the Connection Status Screen.
3. Use the touchscreen to navigate to the Main Control Screen.
4. Pair the remote with the Projector App via Bluetooth.
5. Test brightness, volume, and background music controls to ensure they sync with the projector app.
