I'm new to using Arduino, and I've been trying to hook up a tilt sensor that communicates in RS232. I know the Arduino Duemilanove board uses TTL, not RS232, but I have a converter.
The problem is I can't seem to actually get the data from the sensor. The sensor I'm working should return 2 sets of data as it rotates around the x and y axis. I've other sensors on the board (potentiometer, etc) for practice and have gotten them to work. However when using this tilt sensor, I get just end up with a string of zero's. Now and then, when I move the sensor quickly, i''l get a -1. :-/
My guess is that Arduino is trying to read both sets of data as a single one? I'm guessing there should be a way to tell the board to seperate them, but I haven't been able to find anything. Has anyone ever run into this kind of problem before?
