DIY controller θερμοκρασιας

[apostolis.pan]

Με αφορμη την εργασια που παραδινω αυτην την βδομαδα, καθισα και ψιλομαζεψα κωδικα και σχεματικα .
ο κωδικας.

ο κωδικας ενδεχεται να εχει και καποια junk μεσα , ειναι απο τις αρχες που ειχα πετυχει αυτο που ηθελα αλλα δεν τον ειχα καθαρισει.. βαρεθηκα να τα βγαλω και στην σχολη ετσι θα τον δοσω.. οταν κατσω να τον καθαρισω θα κανω edit.
