Description

Simple timer to control the UV lamp Интервал времени, отсчитываемый таймером, 1...99 минут. Управление тремя кнопками: "decade" и "unit" задают значение, соответственно, десятков и единиц минут, короткое (50 мс) нажатие "start" запускает таймер, повторное нажатие устанавливает таймер на паузу, длительное (> 1 сек) удержание "start" - сброс таймера. Проект в CooCox прилагается.
