Очередной таймер на Attiny85 полив домашнего цветка

Две кнопки управления

Длительное одновременное нажатие 1 и 2 кнопки - переход в режим настроек

В режиме настроек:

кнопка 1 - изменение времени полива от 1 до 9 секунд

кнопка 2 - период полива в днях от 1 до 9

длительное нажатие кнопки 1 - тестовый полив и выход из режима настроек

длительное 1 и 2 - сброс таймеров, начало отсчета от 0 и выход из режима настроек
