Many people are actually ignorant about the ability of the Arduino to display stuff on TV. All you need is right imagination and correct functions to make this happen. John Boxall, owner of troxinstuff.com, have developed an innovative way to create composite video with Arduino and compatible boards. The process is not only simple but comparatively easy, when seen from hardware perspective. Through this post, Boxall guides you in the construction process with minimum hardware and also some of the basic functions is being demonstrated in a video to get started. 

 

 

 

For this project, you will need a 16 MHz microcontroller without a video card, which is a good product in right price. Further, you need to knock out some hardware of our own, to make this project compatible. The connection section is painless and you need to start with locating three pins on the Arduino board, which will be used to output Sync, Video and also GND. 

 

This article also supports the ability to generate audio with certain methods and for those with Arduino Uno/Freetronics Eleven, etc. the procedure is different. Next, make sure that your monitor or television to be used is equipped with a composite video-in socket (jack). Those, who are planning to play with older televisions and have a VCR connected, then use the video-in socket on the VCR. 

 

The schematic for video out is easy as you only need two normal 0.25W resistors and a video lead and if you are not good with soldering into an RCA plug, then simply chop up a standard video lead. Now, the termination of the two resistors is wired to the center core i.e. pin along with GND to the shield. Boxall has made a quick TV-out shield for this project which also includes a thumb joystick.The process of integrating TV-out into the sketch by running through the basic functions, integrated with imagination will give some interesting results.
