Generating analogue video output with an Arduino

Did you know you can generate composite video signals with an Arduino or compatible board? Doing so is very easy and gives you a quick way of displaying data or other information on a large scale - especially as large tube-style TVs can often be found for next to nothing.

All you need is a small external circuit with a couple of resistors and an RCA socket and a new Arduino library written by Arduino forum member uze45. The library allows you to display chracters, simple bitmaps and lines - with which you can create reasonable output as demonstrated below:

To get started you can download the library from here and more discussion is on the Arduino forum. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
