Several arduinos communicating wirelessly

Hello.

Let's brainstorm my idea here. I plan to have one Arduino as a Master this Master will send signals through BT, WiFi or RF whichever is the best alternative. It will send this to 4 Arduino Slaves. Each one of the Slaves will controll One RGB led. So the Master will tell the Slaves what color the RGB should be. All Slaves will get the same data. They will not be controlled individually.

Any of you guys have any experience with this stuff and can point me in the right direction?

Appreciate it!

Look at an Xbee wireless mesh network.

Some idea of required range and RF environment (indoors, outdoors, line-of-sight or not) would be handy....

Range, about 15 meters, indoors, line of sight.
Will look at the Xbee and see what it can do.

NRF24L01 or ESP8266 are way cheaper than Xbees.

Yes but you then have to implement a master slave arrangement with collision avoidance. Messy.

Simply not true. Its a matter of the right protocol.

And what do you think I said? All that is protocol.

It struck be that for a beginner an Xbee would be much easier to implement than writing a protocol. Did it not strike you?

There are no collisions to be avoided if you use the chips features.
