I feel like this is a dumb question, but I am going to ask it anyway.
I have been playing around with the vision examples that come with MRL. These are very cool and work well. The OpenCV GUI is very nice and friendly. It is what brought me to MRL. Playing with faceTracking.py, I see that that the location and size of the box is printed to the python window. My question is this, how would one send this data across a serial port?
