## Quick Start

```bash
cd ~/ros2_ws
source /opt/ros/jazzy/setup.bash
source install/setup.bash
ros2 launch ros2_beginner_demo dashboard_demo.launch.py
```

Open:

```text
http://localhost:8765
```

If the port is occupied:

```bash
ros2 launch ros2_beginner_demo dashboard_demo.launch.py dashboard_port:=8766
```

## 12-Week Project

Open:

```text
src/ros2_weekly_learning
```

Each `weekXX_*` folder contains:

- Knowledge.
- Explanation.
- Case.
- Advanced knowledge.

Run weekly rclpy cases:

```bash
cd ~/ros2_ws
source /opt/ros/jazzy/setup.bash
colcon build --packages-select rclpy_weekly_cases
source install/setup.bash
ros2 run rclpy_weekly_cases week01_case
```

Replace `week01_case` with `week02_case` ... `week12_case`.

## Week 12 rclcpp Case

```bash
cd ~/ros2_ws
source /opt/ros/jazzy/setup.bash
colcon build --packages-select week12_rclcpp_demo
source install/setup.bash
ros2 launch week12_rclcpp_demo rclcpp_demo.launch.py
```

Service test:

```bash
ros2 service call /reset_cpp_counter std_srvs/srv/Trigger {}
```
