1 8085 MICROPROCESSOR PROJECT GOATS AND TIGER GAME MADE BY: AJAY SINGH (15/EC/13) AKASH NIRBHIK (16/EC/13)

2 SYNOPSIS Aim To make Goat and Tiger game using 8085 Microprocessor. Description of Game The figure given represents the game board. The tiger and goats can be placed on the intersections represented by black dots. It s a two player game, one player will control 1 tiger and the other will control 5 goats. The goats and tigers can only be moved along the lines of the board. Gameplay All the goats are placed on the board individually at the beginning. You can only move the goats after you place all the goats on the board. A tiger can capture a goat if there is an empty intersection for the tiger to jump. The tiger wins if it captures two goats, and goats win if they corner the tiger (i.e when tiger is at a position where it cannot move anywhere). There is a time limit of 1 minute for each player to play their turn. Implementation- All the positions on the board are realized through 10 bicolour leds. Each position will have a switch to select the same. The goats and the tiger will be represented with different colours. Two leds will be used to denote the turn. 6 leds will be used to convey time limit(initially all 6 leds will be on at the starting of each players turn, then after an interval of 10 seconds each led will go to off state thus all 6 leds comprising 1 minute). Two 7- segmet displays will show the score of both the players.

3 ACKNOWLEDGEMENT Firstly, we would like to thank Prof. Dhananjay Gadre for his unconditional support and thorough guidance without which this project would not have seen the light of the day. He not only guided us through the project but also played a vital role in helping us relate the theoretical concepts with their practical concepts and instilled in us enthusiasm to LEARN BY DOING. This project was definitely a milestone in our career and we learnt a lot more than just electronics, values of hard work and team work. We would also like to thank our friends and classmates especially Ayush gupta, Tyagi,Ankush and Abhishek Pandey who worked with us and helped at each and every point of time we needed help and assistance. From helping us learn EAGLE, guiding to get PCB ready, helping us through the soldering sessions, getting corrections in software and also final checks on the clock and what not, they were always with us. It was a really good memorable experience working with all of them. We would also like to thank all the staff of the Department of Electronics of Netaji Subhas Institute of Technology for providing us with all the requisites for completion of this project.

13 CONCLUSION EC-316 MICROPROCESSORS PROJECT has been a thoroughly enriching experience. We thank Prof. Gadre for such an opportunity which made us learn in depth about microprocessors and assembly language programming as well as small electronics things which are generally bypassed by the big concepts like led voltages, role of resistors, capacitors etc. It gave a good experience in digital as well as analog electronics. Learning by doing was accomplished. We gathered all the basic knowledge about the microprocessor 8085 and brushed up digital logic concepts which was to be used in this project. The schematic diagram of various components and connections was drawn on PCB software EAGLE. The project gave us a good hand on experience to work on EAGLE.
