Arduino Theft Protection

michu January 5, 2013 6

Nobody likes thieves and thieves (mostly) don’t like if people are at home and watch TV. I thought why not simulate a running TV to deter thefts.

Well I had an old Seeeduino (Atmega 168P) lie around, together with a LiPo Rider Pro and a 6Ah Batterie pack. I added two WS2801 LED pixels and added some lines of Arduino Code – my Arduino Theft Protection was finished.

Put the box in a dark corner of your appartement and it looks like a TV is running.

Here’s an image of the “Arduino Theft Protection” in a box:

A look inside the box:

I published the code in my GitHub repo. I optimised the code to save the battery – instead of delay() my sketch put the Arduino into the sleep mode.

Here is a very bad video of the Theft Protection in action.

Edit 18.1.2013:
Just a note about the power usage, I charged the LiPo Rider only about 1.5 hours, the battery wasn’t fully charged. The box is running each night for about 8h. This means the Arduino Theft Protection Box is running for more than 100 hours until today without a single recharge.

    How bright is it from outside? Through curtains etc?

      You see it quite good from the outside. I don’t have any curtains. however I currently don’t use the full brightness of the led modules if brightness is an issue.

    A very expensive approach to providing some measure of theft prevention. I think it would have been a lot cheaper to simply use an NE555 timer chip (.20c), a CMOS counter/latch and a couple of RGB LEDs.

      Thanks for the idea, sounds like a good 555 project to get started. However I doubt that this project would be finished in 2h when I would use 555 timer chips ;)
