Unfortunately, I can't share the code.
I'm glad you like it :) , There are many ways to make this "automatic" mop mechanism. I did it in that way just because i had some spare parts.Any flip-flop or mechanical switches should also work.
What do you mean by word "procedures"?
CleanBOT doesn't detect any dust , this project is as simple as it could be. If you want to make dust sensor you probably can use some laser or IR diodes with some recievers (photodiodes / phototransistors) to sense the flow of particles.
I dont have any specs of this blower excluding current and voltage rating :~ 1A and ~12V.
Uno R3 has about 18 pins , for this project you need about 30 so it will be tricky to fit on this board, but it is still possible.
