Hi,
i have done one DMX shutter for proyectors using NANO arduino boards.
i follow some examples but for me, this one was the best
http://www.maxwellrosspierson.com/2009/03/20/receive-dmx-512-with-an-arduino/
only two thing:
- the chip MAX485 you can take 5 for free from the fabric.
- When i up load the code to the arduiono i must desconect all the circuit if not always fail the upload( i don´t know why)
i am light tecnician and only say tath there are free programs like magic Q,that can do chases,light efect and save in memory so easy so if you control your leds with
DMX every one tath are used to DMX (all performance tecnician) can use your system.
i hope this help you
