Arduino node

Hi,

Is it possible to use more than Arduino boards and use each board as node? Is it possible that 2 Ardiuno boards can talk with each other? Any idea?

Thanks

Yes - two arduinos can talk to each other.

Thats really great. Please tell me more about it. Can u please put here any example? Or guide me how it is possible?

Thanks

A serial connection between 2 Arduinos is probably the simplest to set up and understand. Print or write to serial on one Arduino and read it on the other. There are other methods such as Ethernet and I2C depending on what you want to do, the distances involved and the hardware that you have.

Ethernet or I2C is good.

Please let me know if all boards with Ethernet can be used or any specific can be used only.

Thanks for your help.

I don't know if any of the official Arduino boards have Ethernet as standard but Ethernet shields are available to plug into Arduino boards such as the Uno, and there may well be third party boards with it built in.

Ok, there are few Arduino board in my school, I guess Uno. Do I need both Uno to make it like node so they can talk with each other?

Can you please give me some code sample on how to write code so 2 Arduino can talk.

Thanks

You could also use SPI , WiFI, Serial via the PC or web or just homebrew a nice fast parallel interface. The one to use is not something like ethernet just because you have heard of it.

You need to work out the amount of data to be transferred and the speed required BEFORE anything else. And the e-net option is more than pocket money.

Not to mention I2C, OneWire, RS485, Bluetooth, VirtualWire, NRF24, and many more.

Agreed.
