Just wondering if anyone has been able to control a DMX lamp through an arduino uno? I have been looking at this tutorial

and have it set up the same way but nothing's working. Sorry if this is a silly question, I'm a bit of a pd newbie. Just wondering what I would need to do to make it work? Thanks!

Can't watch the video right now cause Youtube is throwing a playback error. I've used an Arduino UNO along with the DMX-master shield and library from Tinkerkit, but I think this shield is not being produced any more... This is their google code page https://code.google.com/archive/p/tinkerit/wikis/DmxSimple.wiki it's for the DMX-simple, but it's pretty similar to the master.
You can make a DMX circuit with the max-something IC, but can't remember right now.
What are the issues you're facing?

@pdunicorn It's a Max-485 or RS-485 chip.
But ready made shields are available from £2.99 on ebay....... or more £ with XLR connectors.
"Arduino DMX shield" as a search will find you what you need....

Thanks for the responses. I am about to buy this http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/7798870/ as I feel that would be best, thanks for the advice @whale-av. And @alexandros, the issues I am facing is what I would need to put into the actual patch once I have the shield up and running. I know I need to use the [comport] object but not sure what else. Any help or examples would be fantastic! Thanks for all the help so far guys.

From DmxMaster library SerialToDmx example:

#include <DmxMaster.h>

void setup() {
  Serial.begin(9600);
  Serial.println("SerialToDmx ready");
  Serial.println();
  Serial.println("Syntax:");
  Serial.println(" 123c : use DMX channel 123");
  Serial.println(" 45w : set current channel to value 45");
}

int value = 0;
int channel;

void loop() {
  int c;

  while(!Serial.available());
  c = Serial.read();
  if ((c>='0') && (c<='9')) {
    value = 10*value + c - '0';
  } else {
    if (c=='c') channel = value;
    else if (c=='w') {
      DmxMaster.write(channel, value);
      Serial.println();
    }
    value = 0;
  }
}

In Pd send the message "print 1c255w" to [comport] to write the value 255 to DMX channel 1. That should work.
