Arduino + Maxsonar EZ1 + ProcessingJul 13, 2009 Edit
After resolving my user error with the Maxsonar EZ1 with the help of Bob Gross I moved on to visulizing the data captured. Captuing the output of from the Arduino with Hyper ternimal as a CSV file and importing it in to Excel worked, but I was looking for something more advanced. After a little google (The verb to google (also spelled to Google) refers to using the Google search engine to obtain information on the Web.) I found a simlare project Arduino + Processing: range finder that worked but didn’t look as nice as I wanted.
So I rewrote the code to use arc instead of lines, Change the hue of the arc depending on how close the object is and CSV instead of a proprietary format. It looks much better if you ask me.
