NeoPixel ROS 2 Package for scrap robot

Overview

NeoPixel ROS 2 Package includes two nodes:

• neo_pixel_node: Controls a NeoPixel LED matrix by subscribing to the led_cmd topic.
• led_control_node: Publishes commands to the led_cmd topic to toggle LED colors.

Installation

1. Clone the Repository

   Navigate to your ROS 2 workspace and clone the repository:

   cd ~/ros2_ws/src
   git clone https://github.com/Iredele/matrix_controller.git
   
   # Navigate back to the workspace root
   cd ~/ros2_ws
   
   # Build the package
   colcon build --packages-select neo_pixel_ros2_package
   
   # Source the workspace
   source install/setup.bash
   

2. Usage Run both nodes in separate terminals after sourcing the workspace:

   # Terminal 1: Start the neo_pixel_node
   ros2 run neo_pixel_ros2_package neo_pixel_node
   
   # Terminal 2: Start the led_control_node
   ros2 run neo_pixel_ros2_package led_control_node
   

3. Optional: Manual Control Alternatively, you can control the LEDs manually by publishing commands to the led_cmd topic:

    # Turn LEDs Red
    ros2 topic pub /led_cmd std_msgs/msg/Int8 "{data: 1}"
   
    # Turn LEDs Green
    ros2 topic pub /led_cmd std_msgs/msg/Int8 "{data: 0}"
   
    # Turn LEDs Off
    ros2 topic pub /led_cmd std_msgs/msg/Int8 "{data: 2}"
