Hello,

Here is the simplest example of collecting data into an ArrayList of Integers.

The incoming data is a string (integer); I converted the string to an integer.  
mousePressed() will store 16 integer values and display to screen.

You can easily adapt these concepts with a timer and store data.

There are plenty of examples of timers in this forum.
