[Brian Harms] made his living room window blinds open and close automatically using servos, an Arduino, and a SmartThings Arduino shield. Best of all, it’s connected to his Amazon Echo so that merely saying “Alexa, turn on/off the blinds” will open and close them.
To accomplish the feat [Brian] used two laser cut acrylic gears; one of which was attached to the servo horn, and the other to the long square rod running the length of the blinds. Despite using the bulky Arduino and shield, the finished product is inconspicuous and streamlined, and the single Arduino controls all three of the blinds in the living room. [Brian] answered a bunch of questions on a Reddit thread.
