“A while ago I changed my room around, which made opening and closing the roller blind harder. Like most people, I close the blinds when it gets dark and I have to put the lights on. Similarly, I open the blind in the morning when I wake to let the sun in. The way in which I have changed my room around makes accessing the pull-cord for the blind difficult. I therefore decided that I needed an automatic way of opening and closing the blind. Although not part of my original design concept it can be used as a security device. i.e when on holiday, use the automatic function to open and close the blind to give the impression of being home. The solution was to create a way of automatically opening or closing the blind, when needed, or at predetermined times.”
