Классная идея :) - подсветка низа мебели в коридоре при движении, жду датчики как придут,

разбирайтесь на здоровье (код для attiny85), логика именно как вам и нужна:

Шикарная очепятка!!! Предлагаю осветительные светодиоды так и называть! :)))))

Нубу для начала надо усвоить что темы "помогите" публикуются в разделе "ищу исполнителя". В посте можно указывать "поможите задаром..". (*тут оно нафиг?!?*)

Нет проблем. Пиво?

Убил

Кого?
