I'm trying to use sockets for my real-time switching and sensor reading project. Are there any clear'n'simple examples of their use with an Ethernet shield as the server and mobile phones as the clients.
The ones I have found to date are either very good but very complicated and not very well documented or too simple and reliant on libraries, which I still don't understand fully :-(
Basically, I need to control 4 hydraulic rams from a web page (extend/retract when a button is pressed with a locking mechanism) and then have multiple other screens (from jpg/png pictures) with sensors showing on/off and instructions.
Any help would be VERY welcome. I am used to automotive 'C' programming with some knowledge of C++ but I have to admit that this is out of my comfort zone.
