I wanted to connect my iPhone with physical stuff since one of my research interest was breaking the boarder between the physical world and the screen world. Even though people have been thriving to shorten the gap between these two worlds through touchscreen devices, I believed there were still many possibilities there.
After making an enclosure, I put my iPhone and electronic parts. However, putting p5 sketch with my iPhone and the Arduino required more complex process than I thought. Anyway, I could start with connecting the Arduino and p5 using Serial communication.
I modified former servo application a little and attached an existing p5 sketch with serial communication code which was made at the synthesis workshop.
