If you have ever wanted to create your own laser licking grid like a movie to protect your valuable property, buildings, outhouses. You may be interested in the new Arduino-compatible multi-project laser grid system, which has also been created by Patrick Mitchell of Ottawa, Canada. Patrick is a serial Kickstarter entrepreneur and it will be the sixth electronic project he has launched through Kickstarter. 
Patrick explains: Meet the multi-program Ultimate Laser Tripwire's security settings! This group includes four unique programs! Three of these four programs have a secondary program mode that allows you to adjust functionality. The laser itself is the eye of an invisible person. However, with a little smoke, steam or dust, you can even see the laser! You can pass the mirror or simply laser light directly on one of the four sensors!
