simple $5 3 part USB to DMX adapter using the arduino

i was looking for a way to control some RGB LED Light Strips using connected to a DMX Decoder with my computer and didn't want to buy a expensive USB to DMX adapter so i made this one off the arduino site and it works great:-)

it is quite simple and the MAX485 chip is less then $4

you will need 1x Chip RS485 (Mouser Part #: 700-MAX485EPA) 1x 100ohm Resistor 1x XLR Connector or old cord cut in half

there is no programing required you aren't even using the arduino micro-controller just the USB to Serial Chip so just connect to the RX port on the arduino and install the Enttec driver then start FreeStyler and make a show.

You can install an enttec OPEN DMX Driver and use a free program like FreeStyler to control your DMX Devices
