I'm still pretty new to the Arduino and xBee transceiver. A friend of mine wondered if it was possible to make a wireless quiz buzzer. And of course me without hesitation I said sure. I'm just not sure of the expense.
I was thinking an Arduino with xBee shield as master and 8 xBee remotes. The Master would talk to the receivers as a group. Each remote would be an xBee with its own have address and a simple logic button to send a high pulse the master. When the master receives a high pulse from the group it will buzz and register the number of the remote button on an LCD screen for the team.
He would like to up to 8 teams in competition at one time. Is it possible to run 9 xBees at a time? And do I have to have an Arduino with each remote?
Thanks for the help!!
