This system was born from the need to demonstrate in a simple and practical way the principle of radar or sonar operation, through the reflection of the sound, which is taught in the eighth grade, in Physics and Chemistry classes.

This project is not mine, so if you are interested, you can consult the original on Thingiverse or Youtube.

However, given that I used some material different than what was on the original project, I was forced to change some details of this project. The changes were the use of an different LCD, a new PCB and different connectors. As a result I had to redesign the case cover where the LCD is housed and increase the height of the base. Also the PCB was designed and carved by me, being able to access the project on the EasyEDA platform through this link: https://easyeda.com/lufer2000/mini-radar.

As this system is a prototype, during the assembly of the different components, I verified that there are several corrections to be made. Some at the electronics level, others on components to be printed in 3D. I have already designed new schematics for the electronics but have not applied them yet.
