It is super easy. Just connect the output of the 'cam to the EB500 input and
vice versa. Make sure to set the baud rate correctly, I use the "persist"
modifier in a little program I wrote to change the baud rate. If you are
using the EB500 in a Parallax App Mod header, then make sure to set the pins
on the Stamp as inputs. Write a little program for the Stamp to connect to
the dongle, and then you are in business. I can send you all the Stamp code
I have so far if you like. It is just modified versions of the programs that
come with the EB500. I also have code samples I wrote for doing the same
things with a PIC using PICBASIC Pro on a 16F819/628/88.
It's fun to take pics of my parking lot, 150 feet away and look at them on
the PC. I have been playing with a couple of configurations, like using
Hyperterminal and the Stamp to control the 'cam. It's pretty easy to work
with. Over the summer I hope to develop (with the aid of a PC programming
friend) an app to control our robot and the 'cam via bluetooth. Should be
