circuit with XBee

Eduardo Lytton and I made Rock, Scissor, and Paper game. The game we made will be triggered by start switch. Once, push the start switch, each side generates a random number for rock, scissor, and paper. It will be sent to the other side as a data and the data will be compared with their own data. Depending on the real rock scissor and paper game, the one who wins the game get the light with 'you win' LED.

'ZTerm' and Arduino code represent procedure when game has started.

As a Find & Fix project, I made an indicator. I found the problem that sometimes there is no water and no person to change an empty bottle of water in the right hall at ITP because all bottles of water are in man's room. Therefore, this is the prototype.
Actually, It is supposed to be drained little by little away but because I couldn't make a water cooler, I will pour some water into a cup to measure how much water left in a bottle.
