Remote-X is an open-source universal remote system that combines Flutter, Firebase, and Raspberry Pi Pico to control IR-based devices (like ACs, TVs, etc.). The project aims to provide a smart, flexible, and customizable IR remote system that works across platforms.
- 📱 Flutter-based mobile app interface
- 🔌 Raspberry Pi Pico for IR signal transmission
- ☁️ Firebase integration for cloud command sync
- 🔄 JSON-based remote configuration
- 🧪 Test tools for IR code validation
- 🔧 Simple backend API to bridge the app and Pico

-
Navigate to
backend_api:cd backend_api pip install -r requirements.txt -
Add your Firebase service key (serviceAccountKey.json) — do NOT upload this to GitHub.
-
Run the server:
python app.py
💡 Pico IR Controller
- Flash MicroPython to your Raspberry Pi Pico.
- Upload files from pico_code/ using Thonny or ampy.
- Connect:
- IR LED to GPIO (e.g., GP0)
- (Optional) IR Receiver for testing
📱 Flutter App
Navigate to flutter_app/:
cd flutter_app
flutter pub get
flutter runMake sure the API URL and Firebase configs match your backend.
🔌 Hardware Requirements
- Raspberry Pi Pico
- IR LED (TSAL6100 or similar)
- IR Receiver (like TSOP38238) [optional]
- Resistors, breadboard, jumper wires
- (Optional) Transistor to boost IR LED output
