Given I had no prior experience working with electronic development and circuits wiring, the goal for my project was to take advantage of the new learnt knowledge from class and utilize it on daily application. The idea of the Smart Blind project is to implement sensors onto an ordinary window blind, and with that create interactive movements and responses according to the surrounding environment. By having smart blind installed at home, one can secure personal in-room privacy from the outside, and improve energy saving efficiency by using natural sunlights as a source for interior lighting during the day.
How it works
The basic framework and build of the project is simple. With photo-resistors installed on both sides of a window blind, an Arduino senses the amount of light abundant in the exterior environment and the interior environment. By comparing the values returned by the photo-resistors, the processor will decide how much light to let in by controlling the angles of the blinds with a servo-motor. To improve the accuracy of the motors and the capability of the Arduino board, a motor shield was implemented as an upgrade, and is powered by a 12V battery.
