В очередную уборку в мастерской довелось мне наткнуться на два матричных индикатора 8х8, там же была найдена Mega16, кнопки, макетка. «Какой же ты программист, если за свою жизнь ни разу не написал Тетрис?», спросил .
Конец дня был посвящен тому, чтобы навесом спаять это все хозяйство.
Схема выглядит следующим образом:
К сожалению руки до Тетриса пока не дошли, размялся тем, что написал Пинг-Понг.
Видео работы устройства можно посмотреть тут. Видео
