How to play;

After MCU initialises, RGB LED becomes steady GREEN, thus indicating first player’s move. In secret from the other player, press the chosen button (from left to right in order: ROCK, PAPER, SCISSORS). RGB LED becomes steady RED and now this is the second player’s turn (at that stage of the game, the player may not press the button in secret any more). After the second player’s choice, the RGB LED will flash with the winners colour: GREEN (first player), RED (second player) and BLUE for TIE. Few seconds later, game restarts and you can play again.

I used thus circuit code and arduino. It was my initial code. But people could play Rock-paper-scissor game with one arduino. So, I developed code that can play Rock-Paper-scissor game with two arduinos.

// This is final circuit code and arduino code. I made it possible for two players to play Rock-paper-scissor game. I  took this final one into ThingsCon. in Berlin.



Next steps, this would be the last one for my work. I will make a bracelet like a smart band, which includes a screen and three buttons for Rock-paper-scissor game. This bracelet will make it possible for players to be able to play far away from each other like this below image. To make it possible, I will use the Xbee* to connect two bracelets, which makes it possible to play among more than two plyers far away from each other.

  • *XBee – According to Digi “XBee modules are embedded solutions providing wireless end-point connectivity to devices. These modules use the IEEE 802.15.4 networking protocol for fast point-to-multipoint or peer-to-peer networking. They are designed for high-throughput applications requiring low latency and predictable communication timing.“ So basically XBee is Digi’s own Zigbee based protocol. In layman’s term they are wicked cool, and fairly easy to use wireless modules.Screen Shot 2015-06-19 at 02.07.34

Also, it should be possible to check the players’ location with GPS or other methods. I’m still thinking each one I can use.. I just thought GPS or Piezo circuit, which is used for Nike shoes to check their steps. However, the piezo is not useful outdoors, and Nicolas recommended Pozyx, which can check player’s movement like this below.

However, I still don’t know which is better for developing my idea, because Pozyx can be used indoors and so expensive.. I think, in terms of the museums, they can’t invest lots of money..And when I experimented piezo circuit, it was easy to use, but it will be difficult to check the steps.

For the further development, I think I need to experiment three of these ways..
