If you have been having trouble with rats or mice, check out this innovative project from The Brothers McKenty. The rat trap cleverly uses a hanging basket which falls when a rat is detected, trapping the rat inside. An infrared sensor detects the presence of a rodent, and an RGB LED and a buzzer provide you with useful trap status feedback. The project is clearly documented and is likely to develop both your electronics skills and your general DIY construction skills, with the trap based on a solidly constructed chassis. The addition of Arduino to this rat trap means that it is far more intelligent and effective than any store bought alternatives! To get started on this project check out the following link.
