==========
Though this board has a great single player mode, If you build two, and bond them together digitally you then send one to a friend or loved one so you that you can play chess together over the internet with real chess pieces and only a few seconds of delay. It’s a great way to share some time and to connect with people who are physically distant.
Here are a few more features:
■ Check your moves are legal and warn you when you don't play by the rules
■ Suggest what would be a good next move for you
■ Entirely 3D printable including the chess pieces
■ Very cool looking LED lighting to convey the game status and provide the lighting for evening games
■ Smart control panel which guides you through how to use the board with intelligent backlighting
■ Small and low cost OLED screen to help guide you through using it
■ Powered by USB, so you can connect it to mains or run it from a common USB battery pack for untethered play
The internet connectivity, computer opponent and rule checking are handled by a Raspberry Pi, whilst the lighting and buttons are taken care of by an Arduino Nano.
