Hi,

when i am searching the example code for Ethernet based Home automation in google.All the source codes are relevant to arduino only.

May i know why most of the developers choosing ardunio board and all the examples are in C++. Is there any c examples

 

If you looked inside any commercial home automation product on the market I'd be very surprised if you found a single Arduino. Developers for such products would invariably use proprietary code, so naturally Google would not know about it.
This project seems to use a C compiler.
