# Art-Net Node With Arduino

> my project heavily relies on Matthias Hertel's shield project which is easily understandable, detailed so the real credit is due to him

Original author: Peter_T24 (source: https://www.instructables.com/Art-Net-Node-With-Arduino/)

## Components

- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))
- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Documents and links

- [Code](https://www.instructables.com/Art-Net-Node-With-Arduino/) (code)

## Article

[Matthias Hertel’s shield](http://www.mathertel.de/Arduino/DMXShield.aspx)

[Matthias Hertel’s DmxSerial library explanation](http://www.mathertel.de/Arduino/DMXSerial.aspx)

### **Simple or Advanced**

First you have to decide you just want to make it work, for testing purposes, like on a breadboar, or make it as a final device. The difference is that if you want to use it on the go, I heavily suggest to include the isolated optocoupler and DC converter. If you wish to skip the protection, you can simply go from the Arduino pin 1 to the MAX485 / MAX481 / SN7517 ‘s DI pin. Also that way, the isolated DC/DC converter is can be skipped.

### **Schematic**

The schematic is written down on Matthias Hertel’s site, I could copy-paste it here, but it’s his credit as I said, so go to [Matthias Hertel’s shield](http://www.mathertel.de/Arduino/DMXShield.aspx) and see it there.

The above mentioned shield can send and receive dmx, but we only want to send.

So from [this picture](http://www.mathertel.de/Arduino/DMXShield/DMXShieldSchema.png) we only need the “OK2” labeled 6N137, the MAX481 (which can be replaced with MAX485 / SN7517 they do the same thing), and the DC/DC converter from the top of the picture.

### **Wiring**

You can see on one picture the wiring of the DMX section, and on the other the wiring of the Ethernet section.

### **Arduino coding**

You can download my code below. The Artnet library is also there to download. The DmxSerial library can be downloaded from within the Arduino IDE.

### **Universe and IP address**

In my usecase the IP of the node is fixed in the code, but if you want it to be changeable on the field, a dip switch can be used to select from multiple predefinied adresses.

For universe, the same method, a dip switch can be used.

I know it’s not the most advanced, well documented tutorial, but if have any question, message
