Go is a game played by two players on a 9x9, 13x13, or 19x19 board, in which the goal is to surround more territory than the opponent. It was invented over 2,500 years ago and was utilized as a strategy exercise by Generals.
Today we bring Go to the 21st century by constructing a prototype 9x9 grid with the Attiny85. The Attiny85 sends a reading of the board to the PC – which broadcasts a live-view of the board over the web. Taking into consideration that the chip is not 100% Arduino compatible, we will explore a development environment without the use of an IDE. The Attiny85 has only an 8MHz processor, 8K flash, and 512 bytes of memory, so every bit is essential.
