ARDUINO UNO AND VIDEO EXPERIMENTER SHIELD

[shobha]

HI ALL,
I’m shobha . I’m using video experimenter shield and arduino uno in my project. My project is all about measuring live electricity (i’m using arduino uno for this) and displaying the readings on tv screen periodically( i’m using video experimenter shiled to achieve this) .
My problem is i dont know how will i send values from arduino serial monitor to video experimenter??? second problem is since i’m displaying periodically and measuring electricity per second i dont know where will i store the values???
Can anyone please help me out???? :-

Are you simply asking how to display things on the video output signal? Have you looked at this project:

thanks for the reply….i just wanted to make sure whether the input to the video experimenter is to be a video input or it can be a data from the arduino serial monitor….

You can read data from the Serial line using the pollserial implementation that comes with the TVout library. This way you can display data from a computer to the screen.

See this example of how to read from serial and print to screen:

Nato activates missile shield provides you a shield which protects you from a way of incident. A NATO official told AFP that US President Barack Obama and hisallies “just decided” at a Chicago summit to put a US warship study moose reviews interceptors in the Mediterranean and a Turkey-based radarsystem under NATO command in a German base.
