TV Out with Arduino

This Instructable is for those who would like to use your Arduino to output to a TV. Granted the Arduino is only powerful enough to produce a black and white picture it can still be fun to play with and useful for some projects.

Step 1 Item list

Things you will need:
Hardware
- Arduino
- A TV
- A Protoboard or PCB
- 2 Resistors
1x 470 ohm ( Yellow, Violet, Brown )
1x 1k ohm ( Brown, Black, Red )
- 2x 2-Pin headers ( Only 3 are used but the 4th helps with stability )
- Spare RCA cord you don't mind cutting up
Software
- Arduino Software ( http://arduino.cc/en/Main/Software )
- The TVout library ( http://code.google.com/p/arduino-tvout/ )

The photo is a little blurry. I've re-build it using Fritzing.
Can someone check please if that is correct?

Sorry about the blurrines... Is the yellow wire the ground in your picture?

it looks like it, altho it should have the colors switched it doesnt really matter what the colors are as long as u got them in the right place ^w^

I had the same problem with the compiler , with errors in the library files , the problem for me was theat I play`d around with my Hackduino with atmega8 and when I swicht the 0022 to my Duemilanueve board with the atmega328 it compiled fine , so i gues it dose not like atmega8 :)

[redd.the.cat]

on the tv-out page it says it only works with, atmega 168, 328, 1280, 2560, but no it doesnt work on a dated chip such as the atmega8, i cant wait to try iti just dont have the resistors

[techno guy]

I can't get it to work, there is always some problem. First it was unrecognized stuff and then error compiling, and now more unrecognized stuff. HELP!!!

[JuggaloMemnoch]

Hey... Sorry you're havin problems.. Could you be a little more specific as far as what's goin on? What's it saying is unrecognized?

[techno guy]

usually it says "TVout TV is not a name", now it says "render_setup was not declared in this scope", but by seeing the bottom after trying to verify it, I can tell that after that is fixed, I will have more problems to fix.

[jonnyradu]

Just tested it works with atmega168 boards too

[coder512]

is it possible to render an image ??

[coder512]

rename the file to dot pde extension and try

[Dominion-Network]

I do have a question, how did you solder the Video RCA wire to the protoboard?

[buteman]

The file, when you download it as named as a .tmp file.
When I downloaded it it came out as FNRFNXNGTQVP4MU.tmp
Just rename it as something like tvout.pde
In fact anynameyoulikereally.pde will work

It is the .pde part which you need

and the arduino ide will recognise it and compile it.

one good news the download was ok i just needed to change the format but the code does not compile i listed a few problems



down!!!!!!!!!!!!!!

[fjohn]

its a pretty long error and i cant type all that and cant cpy either but it says smethin abt

cores, udr undeclared .....

this eroor is repeated and with some other errors!!

[fjohn]

hey i tried using the code in the pic and it doesnt seemed to work i dont know why /?? i used ide 18,21,22 and none of them seemed to work and the downloading file that comes in .tmp format help?????

[Dominion-Network]

Could you give us more information, giving details such as any error messages, compiler errors etc would be a great help.

[jman 31]

You might try renaming the file with the proper format. If I remember right, that has worked for me before on here.

[JuggaloMemnoch]

I used the 0022 version of the IDE.. What comes up when you try to complie/upload the sketch?

And I'm sorry this is my first Instructable and I'm not sure why it would come up as a .tmp file... I'll look into it

[Computothought]

This interests me. I still have a couple of old B&W portable battery operated TV's that this project would go great with.
