Design of an inexpensive Ethernet/Arduino-based DMX-control system via network applied to musical fountain

Network to enable or disable a controller using processing of signals has been emerging as a viable solution to many innovative applications in the industry such as; remote control technology, location of wireless sensor network, audio and video processing remotely, in this work the method begins on a website where different users connected to the internet can controlling the music in the fountain, the signal is send via internet to Ethernet shield board, this signal is manipulated in the computer using FFT for the discretization of music after a DSP is applied obtaining a signal sent serially for lamps and electro-valves, finally a Python with simplified examples provided for MATLAB as final user interface is used, this source code is GNU (General Public License), the main contribution of this work is the development of an inexpensive but effective LED-RGB controller based in Arduino with DMX-512 communication protocol, using software as open-source.
