Power Line Communication

[sagnikbasu]

Is there any tutorial on implementationg power line communication using microcontroller like arduino ?

Pretty sure one thread is enough.

When some one doesn't answer your question just keep reasking it in different threads. That doesn't make a forum go to shit fast. Usually if no one answers its because you are in the wrong forum or there is no simple answer.

Best way to communicate over the power line is to take an old school telephone and connect the red and green wires to the black and white wires on the AC side. Add as many receivers as you need communications points. OR you can just directly connect the white and black wires to your arduinos digital inputs... or analog, it won't really matter. It will send exactly one bit of data. Data will be either a 1 or 0 and can be read by the position of your circuit breaker switch. This acts as a digital inverter gate : when the breaker reads 0 or off that is considered a 1. To send an eight bit signal try hooking eight arduinos up to eight different breakers. Get a set of arduinos for each byte you intend to send.
