For a Arduino-based mini-project, another engineering student and I wanted to build on our previous experience while exploring new features such as sound and motion. In just a 1.5-week deadline, we rapidly prototyped a motion detector with a variable frequency alarm based on object distance that can also be turned on and off with a remote.

The housing stand is adjustable to three positions, using teeth-like extrusions on both the stake and stem to connect the box and allow angle adjustments for detecting animals at different heights. A steep learning curve came with integrating new Arduino extensions and libraries used to configure the IR Remote sensor, as this component did not translate directly into TinkerCAD. We also faced challenges designing the stake-to-box connection (our initial threaded-rod concept proved difficult to implement with 3D-printed parts), so we shifted to the extrusion design that better fit our timeline and goals.
