Build a TV Output Cable for Arduino UNO with Just Two Resistors

Necessary tools and machines

Soldering iron (generic)

About this project

Arduino with TV! Yup, it is possible only with two resistors. Let's see the video first:

Arduino boards are pretty useful, but lack an output screen. This project let you allow to write sketches that will output onto a TV screen via an AV Video cable. This is very much a beginner project that just about anyone can do!

Hardware

First off, you need to add the resistors inline to some hookup wire, according to this diagram:

Your RCA cable will have 2 wires in it, a ground wire and a vid (Video) wire. Generally the vid (Video) wire is sheathed in plastic and the ground wire is not.

Depending on your setup and what you want to achieve (audio or video etc) refer to the following hookup guide:

Connection Diagram

I used heat-shrinkable tubing to make sure that everything was electrically insulated and to provide a little more strength in the solder joints:

You can then plug your new Arduino TV out cable into a TV or monitor and then plug the hookup wires to the Arduino.

Different Arduino boards have different setups with the Sync/Video, but you can rest assured that Ground will always go to the Arduino GND pin.

Software

Step 1: Arduino-TVout Library

Download Arduino-TVout library.

Step 2: Install Library

Open Arduino and goto "Sketch" menu / "Include Library" / "Add .ZIP Library..." and select the library downloaded in Step 1.

Step 3: Compile & Upload Sketch

From "File" menu / "Examples" / "Arduino-TVout" and select "DemoPAL" and upload it.

Done!

Now, connect up the Arduino and give it a go!
