I'm trying to find a way to control remotelly, an Arduino Ethernet Shield/Arduino direct by my Django webpage. I mounted a schema, see below how I want it works:
Remote User ---> WEB Page ---> Python Web Server ---> Arduino Ethernet Shield ---> Arduino ---> LED
In this case, make a python web page (made with Django or whatever) to send commands directly to the Ethernet Shield to have a nice webpage with CSS, etc. and need not to be connected to the Arduino into a USB port of my PC, but in any place, by network cable.
I did a search around WebSockets, but I have not found a way to send a command to the Arduino and receive a reply from him.
I made myself clear?
