Pametna budilica

Osnovna škola Zamet

Pametna rasvjeta s pametnom budilicom. Kontrolira se s Blynk aplikacije, a gasi se prekidom laserske zrake usmjerene u fotootpornik.

Video snimka

Izrada projekta

Laserska dioda i foto otpornik. U trenutku prekida laserske zrake dolazi do promjene izlazne vrijednosti na foto otporniku. Posljedično, gasi se svjetlo pametne budilice.

Blynk aplikacija i pametna budilica.
