I'm at the conceptual stage of a project and would like some advice. The project can best be described as a game. The "Whack-a-Mole" game is a pretty close approximation of what I'm trying to do except the "moles" are further apart. If you don't know what this game is, watch this 22 seconds of video: https://www.youtube....h?v=D0n8N98mpes
There will be n number of devices in the network and one master controller. I'm thinking the controller will be a laptop, but I'm open to other ideas.
Each device will "display" according to an algorithm running on the master controller. If the mole is whacked while its displayed, a signal should be sent back to the master controller with the time it was whacked.
So my question is what is the best way for the master controller to communicate with the moles? After doing some research, it seems to me that each mole should be an N+2 with a Edimax BR-6258n wireless router running the NeonMika webserver. However, my concern is speed. Would Bluetooth be a better option or maybe one of the Xbee protocols? What about using a Mini instead of a N+2?
