добрый день.изввините за делетанство.есть код необходимо только назначить пин для зумера.где это не знаю
буду рад любой помощиэ

Это важно. Заказчик было истерику устроил - подключил активный вместо пьезо (по условию) и говорит что хрипит. А затем включил дурку, типа, я не копенгаген. Повнимательнее.
спасибо важное замечание.я связался с автором и он переделал код зумеры есть и активные и пассивные.обновленный так же не работает издает несколько коротких сигналов и все при этом в маниторе порта растояние показывает правильнбуду признателен сообществу высказать свое компитентное мнение и конкретные ошибки указать.

Моё “компитентное” мнение: судя по первому посту, код Вы вставлять умеете, а значит, мы имеем дело не с ошибкой а с осознанным, циничным издевательством над сообществом.
