What Is a LED stairs controller?
The video shows how it works!
Step 1: The idea
The main idea was taken from Alan's Parekh video, many thanks to him.
The idea was this: When I get up at the middle of the night to get some food, I have to go down the stairs from the top floor and then up the stairs again. One day I've decided I need an automatic backlight so I don't turn all the lights on and wake my family up. Plus I wanted a nice smooth turning on and off so it doesn't irritate sleepy eyes. Also the device had to be error-resistand, ignore sunlight, remotes and other things.
And so in order.
