S17: Interactive Snake and ladder

Project Title

Snake and Ladder

Abstract

This project aims to bring the fun and simplicity of snake and ladder game with some new features. It is a snake and ladder game using SJONE board, LCD and 2 wireless remotes. LCD display is connected to the SJONE board will display the game grid. It will also have the multiplayer feature that will allow more than one players to play the game using wireless remotes simultaneously. This project explores a new dimension in the traditional snake game to make it more interesting and challenging.

Objectives & Introduction

This game aims to change the way people think of traditional snake game. It will offer the experience of commercial multilayer games to the player retaining the simplicity of traditional snake game.

The major objectives of this project are:
- To create a snake and ladder game that will have all the functionality of traditional snake and ladder games.
- Introduce multiplayer functionality in the game that will allow several players to play a game simultaneously. It should be able to give the experience of a real time multiplayer game to the players.
- To introduce Speech output for events.

Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

Overall System

The overall system is divided into 3 parts:
- game image display(LCD): the snake and ladder image grid is mounted on the 7 inches LCD screen.
- wireless SJONE board: the antenna is connected to SJONE board to transmit and receive signal from master. The basic use of the SJONE board with antenna is to through dice.
- text to speech module: based on the actions performed the audio file gets executed. To make a game more effective and attractive.

All these functionalities work in parallel and have the same priorities.

Overall System Flow Chart

Hardware Design

Schematic Diagram

Below is the schematic diagram for the project. It includes the power supply, interface for LCD controller and text to speech module.

PCB Layout

Below is the PCB layout developed using Eagle PCB and Altium designer.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

PCB

Below is a list of challenges we faced during PCB designing:

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

We successfully completed our project of interactive snake and ladder by writing various modules and our mentioned overall objectives of it. We learned a lot about Sjone board and LPC1768 micro controller. we have added extra function in project so that multiple players (more than 2) can play the game simultaneously by just connecting antenna and flashing the code on SJone board. Hence this project increased our knowledge of software and hardware.
