I’m closing of this project as I think that with the current configuration I will not be able to achieve what I want.
\nBy closing this project I will kick of a new one(Version 2) which would be a bit more complicated from the hardware and programming point but at least it will give me more freedom. The new version of arduino automatic stairs is already being developed and I will post a new post soon(watch this space<\/a>). For those of you who are still interested in this project here is a draft code:<\/p>\n
