I have noticed this for some time and wanted to put it finally on the forum in the hopes someone can clarify what is happening and offer a solution.
m using the decimianove, XP, USB 1.0, FTDI drivers properly installed, and am running using Pduino .5 beta 8 into puredata.
I power up the computer, plug in the arduino, open the puredata, open the Pduino arduino patches, see the arduino, open the com/serial port, and see the analog pins dancing wild numbers across the display.
Im guessing these are voltages picked up from the analog ins.
I hook something up to pin number 0 and all other pins change to the voltage readings of pin 0 with nothing hooked up to them.
I simply want them to show no numbers--ie-no erratic voltages-- when nothing is hooked up.
can someone enlighten me as to how to do this and as to why the arduino seems to be picking up ghosts from space and showing it as data?
would be much appreciated. -Steven
