Arduino Meet TouchDesigner: Serial Communication
I had been putting off attempting serial communication between Arduino and TouchDesigner for a bit due to the trouble I had linking up Arduino with Processing, but thankfully the transfer of information seemed to be much smoother between these two.
The examples on the touch 088 wiki page were unbelievably helpful. Though getting information back to the Arduino is a bit more headachesville. I'll be playing with that more in the future.
