This is a project that can be used to demonstrate the principles of a radar device used for detection of objects at a distance. It uses 3D printed parts as a housing for electronics using an Arduino UNO R3 microcontroller, LCD screen, Ultrasonic Module, and an inexpensive servo motor. A 23-page set of instructions and assembly details along with the CAD files used to create the model objects is included.

PLA can also be used for this model. A document that covers the model, the parts, the wiring, and the assembly is the UltrasonicRadarProject.pdf file included.

I loosely designed this project from “Portable Radar Using Arduino”, by Alsan Parajuli. I found his project at https://theiotprojects.com; however, it appears to no longer be accessible. I used FreeCAD to create the housing for all the electronic components. I used the Windows Arduino IDE to write the software for the UNO that controls the electronic parts.
