The problem we want to approach in this paper is related to window blinds. Sometimes, when forgotten open, the light can disrupt the sleep in the morning or it can burn the plants by the window. Although there are already many existent solutions for smart window blinds, we want to create a smart light manager for every house that will be able to adjust the level of light by the user's desire. In our project we are going to use light sensors(inside and outside the house) in order to open window rollers or turn on/off the leds based on the constraints set by the user in the mobile application. For the project, we use Arduino Nano, servo motors, leds and an artificial crafted environment for testing.
