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 мозг.
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.
