Ping-Pong на AVR

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.
Ping Pong на AVR

Схема выглядит следующим образом:
Ping Pong на AVR

К сожалению руки до Тетриса пока не дошли, размялся тем, что написал Пинг-Понг.
