Laser Tripwire takes a Photo, Uploads it to Twitter
The laser tripwire project is superb project for both experienced and brand new Arduino enthusiasts. It combines both hardware, software, and communicating between the two. The simple project captures a snapshot of an unauthorized entry and alerts the homeowner via Twitter. The security project is built around an Arduino board, a laser pointer, a photoresistor, and a webcab.
The laser is reflected across a doorway into the photoresistor which is connected to the Arduino When the door is opened, it trips the beam which sends a signal to the Arduino. The Arduino forwards the signal to the computer which then executes a program written in Processing. The software then logs into Twitter as it captures a photo from the webcam and then posts a link to the photo as we ll as the exact time of the break-in. Check out the detailed steps and the source code to setup a dirt simple DIY security system.
