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.
Roles & Responsibilities
- Hardware and PCB designing
- Speech Module Interface and Algorithm
- LCD Interface and Game board Algorithm
- Wireless Communication

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
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:
- For designing the PCB, we use EAGLE software. Which is new for us and that was a challenging task to draw layout.
- We faced Assembly issues like dry solder on pins. So, we re-soldered the component pins.
- There was an insufficient bypassing on PCB hence we added required value of bypass capacitor on board.
- While testing PCB, we find a problem of shorting of a track so we use a multi meter to perform a continuity test and verification on the pins and fixed that.
LCD display
- The main challenged faced related to display is to print a snake and ladder picture grid. Also, to determine exact coordinates of snake and ladder on grid is one of the challenges. this a tough job but we manage to do that. Tried to achieved high refresh rate on LCD to get real time display effect.
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.

Acknowledgement
We would like to Thank Preetpal Kang. We used his API's of free RTOS which help us a lot to write a code for each module. The knowledge he has given us about all the interfacing buses like SPI, UART, I2C helped us in using that in our project and will help in near future.
