Ethernet TV

After my last success with the Serial TV, I’ve got the idea making it possible for you to the television using a browser.

I’m still using my Serial TV, but now it’s connected to an Arduino instead of the computer. The Arduino has an Ethernet Shield on top, and it’s programmed to make a homepage with a text-field and a submit button!

Here is some pictures of the project:

Last week I recieved the Arduino Ethernet Shield – http://www.arduino.cc/en/Main/ArduinoEthernetShield
There were all ready complete examples provided, so it was very easy to get started.
Then I thought it would be nice to have a Ethernet DMX Controller, so i could type the IP-Adress of the Ethernet Shield in explorer, and from there control my movinghead (Stairville MV250H)

Then I found this page showing how to use an MAX485 and the Arduino as a DMX interface – http://iad.projects.zhdk.ch/physicalcomputing/hardware/arduino/dmx-shield-fur-arduino/
I tried it, and it worked – And the Arduino could communicate with my movinghead.

Then I combined the Ethernet example and the DMX example, to make a HTML Page where i could click on different buttons to change the DMX values that would be sent to my movinghead.
Try it out yourself… You need a MAX485, follow the link above on how to connect it to the Arduino. Just use pin 3 instead of pin 11, as the Ethernet shield uses Pin 9 to 13!

Here is the Arduino code:

#include 

#include 
// include pin definition library -----------------------------------------------

#include "pins_arduino.h"
// variable definitions ---------------------------------------------------------

int sig = 3;       // DMX signal pin - DO NOT CHANGE
// network configuration.  gateway and subnet are optional.

byte mac[] = { 0x00, 0x12, 0x34, 0x56, 0x78, 0x90 }; // Change this to the MAC the Ethernet shield should have

byte ip[] = { 192, 168, 1, 1 }; // Change this to the IP-Adress the Ethernet shield should have
