Go to the official page here and download Processing. Then copy the code from below and paste it in processing. Connect the Arduino to the PC and see which COM you are using. Make sure you uplaod the Arduino code from above. Then run the processing code. The LIDAR will start rotating and ploting the distance to the screen.
