Pametne osvijetljene stube

Zajednica tehničke kulture Valpovo-Belišće

Model osvijetljenoga stubišta koje uključuje rasvjetu na stubištu u odnosu na mjesto gdje osoba trenutno stoji. Osvijetljena je stuba na kojoj se osoba trenutno nalazi te jedna stuba ispred i jedna stuba iza trenutne stube. Koristimo Arduino MKR1000, 10 LED-ica te ultrazvučni senzor udaljenosti. Mobilna aplikacija prikazuje udaljenost predmeta od senzora udaljenosti.

Izrada projekta

Predmet je na petoj stubi i zbog toga svijetle četvrta, peta i šesta stuba.

Pozadina projekta. Stube su ispisane na 3D printeru i dimenzija su 70x30x10mm.

Pogled odozdo.Stube u sebi imaju ugrađene 5mm zelene svjetleće diode.

Projekt je modularan, a lemljene su jedino svjetleće diode i otpornici i to na žice za prototipiranje kako bi se mogle isključiti.

Blynk program prikazuje udaljenost predmeta od senzora.

Mobilna aplikacija

Prikaz udaljenosti objekta od senzora.

Shema projekta

Shema spajanja vidljiva je na poleđini projekta i vrlo je jednostavna.
Na MKR1000 spojeno je 10 svjetlećih dioda na ulazno-izlazne pinove 1-10 dok je na pinove 11 i 12 spojen echo i trigger pin s ultrazvučnog senzora udaljenosti.
