# Getting Started
|
|||
|
|
|
|||
|
|
Velxio is an open-source Arduino emulator that runs entirely in your browser. Follow these steps to simulate your first Arduino sketch.
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## Option 1: Use the Hosted Version
|
|||
|
|
|
|||
|
|
No installation needed — go to **[https://velxio.dev](https://velxio.dev)** and start coding immediately.
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
## Option 2: Self-Host with Docker
|
|||
|
|
|
|||
|
|
Run a single Docker command to start a fully local instance:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
docker run -d \
|
|||
|
|
--name velxio \
|
|||
|
|
-p 3080:80 \
|
|||
|
|
-v $(pwd)/data:/app/data \
|
|||
|
|
ghcr.io/davidmonterocrespo24/velxio:master
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Then open **http://localhost:3080** in your browser.
|
|||
|
|
|
|||

|

|
|
|
|||
|
|
## Option 3: Manual Setup (Development)
|
|||
|
|
|
|||
|
|
**Prerequisites:** Node.js 18+, Python 3.12+, `arduino-cli`
|
|||
|
|
|
|||
|
|
### 1. Clone the repository
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
git clone https://github.com/davidmonterocrespo24/velxio.git
|
|||
|
|
cd velxio
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 2. Start the backend
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
cd backend
|
|||
|
|
python -m venv venv && source venv/bin/activate # Windows: venv\Scripts\activate
|
|||
|
|
pip install -r requirements.txt
|
|||
|
|
uvicorn app.main:app --reload --port 8001
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3. Start the frontend
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
# In a new terminal:
|
|||
|
|
cd frontend
|
|||
|
|
npm install
|
|||
|
|
npm run dev
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Open **http://localhost:5173**.
|
|||
|
|
|
|||
|
|
### 4. Set up arduino-cli (first time)
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
arduino-cli core update-index
|
|||
|
|
arduino-cli core install arduino:avr
|
|||
|
|
|
|||
|
|
# For Raspberry Pi Pico support:
|
|||
|
|
arduino-cli config add board_manager.additional_urls \
|
|||
|
|
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
|
|||
|
|
arduino-cli core install rp2040:rp2040
|
|||
|
|
```
|
|||
|
|
|
|||
|

## Your First Simulation
|
|||
|
|
|
|||
|
|
1. **Open the editor** at [velxio.dev/editor](https://velxio.dev/editor) (or your local instance).
|
|||
|
|
2. **Select a board** from the toolbar (e.g., *Arduino Uno*).
|
|||
|
|
3. **Write Arduino code** in the Monaco editor, for example:
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
void setup() {
|
|||
|
|
pinMode(13, OUTPUT);
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
void loop() {
|
|||
|
|
digitalWrite(13, HIGH);
|
|||
|
|
delay(500);
|
|||
|
|
digitalWrite(13, LOW);
|
|||
|
|
delay(500);
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
4. **Click Compile** — the backend calls `arduino-cli` and returns a `.hex` file.
|
|||
|
|
5. **Click Run** — the AVR8 emulator executes the compiled program.
|
|||
|
|
6. **Add components** using the component picker (click the **+** button on the canvas).
|
|||
|
|
7. **Connect wires** by clicking a component pin and then another pin.
|
|||
|
|
|
|||
|

## Loading an Example Project
|
|||
|
|
|
|||
|
|
1. Click **Examples** in the navigation bar.
|
|||
|
|
2. Choose a project such as *Blink*, *Traffic Light*, or *LCD 20×4*.
|
|||
|
|
3. Click **Load** — the code and components are imported automatically.
|
|||
|
|
4. Click **Run** to start the simulation.
|
|||

## Troubleshooting
|
|||
|
|
|
|||
|
|
| Problem | Solution |
|
|||
|
|
|---------|----------|
|
|||
|
|
| `arduino-cli: command not found` | Install `arduino-cli` and add it to your PATH. |
|
|||
|
|
| LED doesn't blink | Check the browser console for port listener errors; verify pin assignment in the component property dialog. |
|
|||
|
|
| Serial Monitor is empty | Ensure `Serial.begin()` is called inside `setup()` before any `Serial.print()`. |
|
|||
|
|
| Compilation errors | Check the compilation console at the bottom of the editor for full `arduino-cli` output. |
