I have an ultrasound module that I need to use (not buying another) and was wondering if there is a way of using it with Arduino. No problem if not, as it has its own board and uses a serial connection.
Here is the datasheet:http://www.milinst.com/robotics/5_120.pdf
It comes with its own board to drive it, and timing, then sends as serial message.
My only thought for linking into Arduino, is that I'm using the serial port for a touch screen and wondering if there would be a conflict (and the need to add an extra serial port pci card)
