I am a new to processing and i am stuck at a point in my program. I am reading values from a ultrasonic sensor using arduino and ploting a graph in processing. Later on i am storing this data into a csv file but now when i run the program again i want a new csv with a different name to be created. What is happening at the moment is that the new readings get overwritten in the previous file. I have no clue how to do it. Please help!!
