JESUS this is i think too complicated for me. I will use only the simple method from supernova.

It is most possible that if you use a simple error correction and not something complicated, your construction will fail. There must be a quick "chat" between sender and receiver before the receiver goes into action.

Hamming code is simple? It is not! And why do i need to have a "chat"? Is there something needed for this?

You need the chat because you need to be sure if the receiver has really received the data you sent. You do not want to fail. Because if you click to open the light and does not open is ok. But if you have an automation to shut the heater down and does not shut it with the first try what do you do? That is why u need the chat

Hamming code IS simple and so is the "chat" thing we discuss. This is the protocol. You need to be sure that the receiver heard you...

Of course you can, but this will not elimenate the errors.

The RS232 has the odd and even error correction but i do not think this is what you really need. After all, when you connect a device to computer, the communication is 2-way. Except of course some old printers

Of course you can. As long as you have a clear chat. But this protocol is used basically for between host and client communication, not a host with multi client communication. You should try something else instead.

If you are trying to avoid making a good protocol, then you should make a smaller project like a sender and receiver for example, ton a net with 100 pics connected because you will fail 100% and maybe disappointed.

Maybe i should try something easier for a beginning. You are right. :/

Try first some pic 2 pic interconnection or even IR transiever and then go on. One step at a time
