Overview
This project is an mbed-powered electronic chess console. A chess board/pieces are displayed via LCD, and moves are made using joystick and buttons. The current player is indicated with an LED, and his remaining time is displayed via 7-segment display. Using mbed RTOS threads, the software handles user input, chess rules, graphics, and LED/sound feedback. This implementation includes a custom electronics housing and a mobile battery for powering the mbed.
