What is ROS? "The Robot Operating System (ROS) is a flexible framework for writing robot software. It is a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms." - ros.org
For ROS, you can find a driver node to help users integrate our RPLIDAR into your robots. It is available on GitHub.
What is Arduino? "Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board." - arduino.cc
For Arduino users, a driver library is now ready. Arduino users can use this library to fetch RPLIDAR data just as the standard RPLIDAR sdk does. Also, you can find related examples! The library is included in RPLIDAR development kit SDK. You can find its source code at GitHub. Enjoy making!
