Hi,
I don't know. I loaded the firmata sketch on the sanguino and the extended example of Firmata VB in VB express and ran the debug and couldn't get any LEDs connnected to the digital pins to light up. I made all the ditital pins output and toggled them all.
I choose the same com port (via usb) that I used to load the skecth.
My goal is to build an automated brewery controller similar to the brewtroller http://www.brewtroller.com/ but I want to have most of the controls from a laptop. Of course my goal is way beyond my reach at this point but I expect to learn alot from it.
The system will have 4 temp sensors, 3 presure senors, 5 pneumatic valves, 2 pumps and 2 heating elements.
