Breadboard Demo

Description

The Breadboard Demo is an informal but mandatory event. Its purpose is to show your instructor and TA a circuit that you have been working on in the lab for your project. It is expected that the circuit will include the microprocessor you will be using in your project (it can be mounted on a development board) and it will be connected to a project subsystem. The microprocessor should have a program downloaded onto it that allows it to communicate with the subsystem, i.e., control the subsystem or receive data from it. It is expected that the power source for the circuit will be a laboratory power supply. The function of the subsystem should be demonstrated. The commands or data should be displayed on a pc or other display means. You should be able to explain how the circuit is used in the project and be able to justify design choices. A Breadboard Checklist will be provided and filled out.). Use the following format:

    See the Breadboard Demo Rubric for specific details.

Grading

Full Credit (20 points) will be given if the circuit works, is of adequate complexity, and a good explanation of its features is given by the team. Point reductions will be given if the circuit fails to work (-2), lacks complexity (-2), or seems inappropriate for your project (-2). The Breadboard Demo is a team activity and results in a team score.

Assistive Chessboard

Featured Project

Problem: It can be difficult for a new player to learn chess, especially if they have no one to play with. They would have to resort to online guides which can be distracting when playing with a real board. If they have no one to play with, they would again have to resort to online games which just don't have the same feel as real boards.

Proposal: We plan to create an assistive chess board. The board will have the following features:

-The board will be able to suggest a move by lighting up the square of the move-to space and square under the piece to move.

-The board will light up valid moves when a piece is picked up and flash the placed square if it is invalid.

-We will include a chess clock for timed play with stop buttons for players to signal the end of their turn.

-The player(s) will be able to select different standard time set-ups and preferences for the help displayed by the board.

Implementation Details: The board lights will be an RGB LED under each square of the board. Each chess piece will have a magnetic base which can be detected by a magnetic field sensor under each square. Each piece will have a different strength magnet inside it to ID which piece is what (ie. 6 different magnet sizes for the 6 different types of pieces). Black and white pieces will be distinguished by the polarity of the magnets. The strength and polarity will be read by the same magnetic field sensor under each square. The lights will have different colors for the different piece that it is representing as well as for different signals (ie. An invalid move will flash red).

The chess clock will consist of a 7-segment display in the form of (h:mm:ss) and there will be 2 stop buttons, one for each side, to signal when a player’s turn is over. A third button will be featured near the clock to act as a reset button. The combination of the two stop switches and reset button will be used to select the time mode for the clock. Each side of the board will also have a two toggle-able buttons or switches to control whether move help or suggested moves should be enabled on that side of the board. The state of the decision will be shown by a lit or unlit LED light near the relevant switch.
