This is a short video of Youtuber Caliixxs demonstrating the door sensor he built using an Arduino, infrared sensor, and Adafruit Music Maker Shield to play the various bass riffs from Seinfeld whenever the door is opened. I have a mechanical door sensor. And that sensor is a metal folding chair leaning against the door so if anybody opens it the chair falls and I come running with a bat because nobody should be opening the door in the first place. "But I'm from the plumbing company." Plumbing company? Wait a minute....is this a p0rno?! Are we about to do it?! "I'm seriously from the plumbing company, your landlord sent me." Sooooo....start unbuttoning my shirt real slow and sexy or what?
Keep going for the video.
Thanks to Dumbadogong, whose door sensor is a barking dog.
