Long Demonstration:

Users can battle with other users in 1 vs 1 battleship using their mbeds. Battleship is a guessing game for two players. Players alternate turns calling "shots" at the other player's ships, and the objective of the game is to destroy the opposing player's fleet. The first to get 17 hits on the enemy fleet is the victor.

Supplies

1. mbed (x2) 2. Adafruit Bluefruit LE UART Friend (bluetooth) (x2) 3. uLCD-144-G2 (LCD screen) (x2) 4. Raspberry Pi 3 with appropriate cables 5. Computer for forwarding data (x2) 6. Phones to connect to Bluetooth

mbed Pinout

mbed

The mbed is first connected to the computer and the phone. A computer is used to connect the player to other players on the network and the a blue module allows the player to give commands to the mbed. The mbed displays the game on the LCD screen and controls the game state.

Server

The Raspberry Pi acts as a hub/sever for players to get connected to each other and passes packets to their appropriate destination with TCP connections. A 4 char packet is sent from the clients through the server to determine the Cartesian coordinate, hit, and game state. The server also determines which player goes first.

Extra Features

• The server can handle multiple games at once because the server creates a new thread to handle each individual game.
• We also made a simpler pc version of the game that prints to command line and battle ships are place by changing the matrix in the file.
• Pc players and mbeds players can be connected to a game together.

Code

• Import programIoTBattleship

  Battleship using serial connections and wifi.
