# Gambit

[![Build](../../actions/workflows/build.yml/badge.svg)](../../actions/workflows/build.yml)

Gambit is an open-source robotic chessboard that moves pieces using magnets and detects their positions with reed switches. It uses a T-Bot mechanism with an electromagnet for precise piece movement and a reed switch matrix for accurate position detection. The board is powered by an Arduino Nano ESP32, which allows for future enhancements like Bluetooth and Wi-Fi connectivity.

## Features

- **Simple Hardware**: Arduino Nano ESP32 with simple components available on Amazon

- **Easy Movement**: T-Bot mechanism with off-the-shelf parts

- **Built-in Chess Engine**: Runs a Nibble Chess derived ches engine directly on the ESP32

- **Chess Notation Support**: FEN, LAN support for compatibility (Working on PGN)

- **Modern Development**: PlatformIO for better code organization and testing

- **Wireless Control**: Bluetooth connectivity for app integration

## Goals

- **Affordable**: Uses widely available, low-cost components

- **Compact**: Competition-sized board (approximately 60cm x 60cm)

- **Open Source**: All designs and code freely available to modify and improve

- **Reproducible**: Simple enough for hobbyists to build

- **Standalone**: No external computer required to play
