To get stuff to appear on your TV screen using the TellyMate is easy. You just send the appropriate serial command to the device and voila!! Read the instruction manual.
Right, but The_Bongmaster doesn't have the TellyMate yet, he was looking to see if he could build his own on a breadboard and test it out if I read it correctly.
new version of the TellyMate Shield ... can send back data to the Arduino.
Interesting, what kind of data and how can it be used?
