Art-Net to DMX converter with Arduino.
This code required a ethernet interface and DMX (RS485) transceiver.
By default it uses the same pins with Official Arduino Ethernet Shield shown here. We are currently using third-party ethernet interface with 10, 11, 12 and 13 pins and it works fine.
We are using RS485 (Datasheet) as converter IC. Connection pin on arduino defined as DMX_OUT_PIN in the code.
Issues and PRs are welcome.
