## Features
### Signal Transmission Methods
- **Flashlight**: Utilizes your device's camera flash to transmit visual signals.
- **Vibration**: Sends tactile signals through device vibration.
- **Audio**: Generates clear audio tones at 700Hz frequency.
- **Screen Light**: Maximizes screen brightness to create visual signals in darkness.
### Core Capabilities
- **Background Service**: Continue signaling even when the app is minimized or screen is locked.
- **Message Customization**: Send any custom message in Morse code.
- **Adjustable Speed**: Choose from slow, medium, fast, or custom transmission speeds.
- **Morse Code Decoder**: Convert received Morse code into readable text.
- **User Preferences**: Independently toggle each signaling method based on your needs.
## Practical Applications
- **Emergency Situations**: Signal for help when conventional communication is unavailable.
- **Outdoor Activities**: Hiking, camping, or sailing where cellular service is limited.
- **Educational Tool**: Learn and practice Morse code with visual and audio feedback.
- **Accessibility**: Provide alternative communication methods for users with special needs.
## Technical Specifications
- Optimized for minimal battery consumption.
- Supports Android 6.0 (Marshmallow) and above.
- Requires permissions for camera, vibration, and audio output.
## Usage
1. **Emergency SOS**: Press the SOS button to immediately begin transmitting the international SOS signal (... --- ...) .
2. **Custom Message**: Enter your text in the input field and press "Send" to convert and transmit.
3. **Decoder**: Navigate to the decoder screen to translate incoming Morse code signals.
4. **Settings**: Customize transmission speed and toggle different signaling methods.
## Permissions
- **Camera**: Required for flashlight functionality.
- **Vibration**: Required for haptic feedback.
- **Notification**: Required for keeping background services alive.

# SOS 手電筒: 進階摩斯電碼通訊工具
SOS 手電筒 App 將您的智慧型手機轉變為摩斯電碼信號裝置，能夠同時通過多種管道傳輸緊急訊息或自定義文字。
## 功能特色
### 信號傳輸方式
- **閃光燈**：利用設備的相機閃光燈傳輸視覺信號。
- **震動**：通過設備震動發送觸覺信號。
- **音效**：生成清晰的700Hz頻率音頻。
- **螢幕光源**：最大化螢幕亮度，在黑暗中創建可見的信號。
### 核心功能
- **背景服務**：即使應用最小化或螢幕鎖定，仍能持續發送信號。
- **訊息自定義**：以摩斯電碼發送任何自定義訊息。
- **可調速度**：選擇慢速、中速、快速或其他自定義傳輸速度。
- **摩斯電碼解碼器**：將接收到的摩斯電碼轉換為可讀文字。
- **用戶偏好設定**：根據需求獨立開關每種信號傳輸方式。
## 實際應用
- **緊急情況**：當常規通訊不可用時發出求救信號。
- **戶外活動**：在行動電話服務有限的遠足、露營或航行中使用。
- **教育工具**：通過視覺和聽覺反饋學習和練習摩斯電碼。
- **無障礙功能**：為有特殊需求的用戶提供替代通訊方法。
## 技術規格
- 優化最小電池消耗。
- 支援Android 6.0 (Marshmallow) 及以上版本。
- 需要相機、震動和音頻輸出權限。
## 使用方法
1. **緊急SOS**：按下SOS按鈕立即開始傳輸國際SOS信號 (... --- ...)
2. **自定義訊息**：在輸入欄位中輸入文字並按下「發送」進行轉換和傳輸
3. **解碼器**：導航至解碼器畫面以翻譯接收到的摩斯電碼信號
4. **設定**：自定義傳輸速度並切換不同的信號傳輸方式
## 所需權限
- **相機**：閃光燈功能所需
- **震動**：震動反饋所需
- **通知**：需要讓背景服務長時間運作
