Implementation of a metal detector with discrete components and Arduino

The goal of this unit is to implement a commercial metal sensor using Arduino as control technology. We are going to build a prototype that in the presence of metals will emit a sound and acoustic signal. 

Through this unit we want to improve the computational thinking of our students to favor critical thinking, lateral thinking and programming skills.

The ultimate goal is for our students to start thinking like scientists or computer scientists when solving problems. These types of exercises based on the creation of algorithms and sequences of instructions facilitate abstract thinking and allow students to develop solutions by breaking them down into the appropriate parameters to make technological development possible.

This type of thinking can be applied to any scientific field or even to daily life. In the future, students will be able to transfer this knowledge to their jobs or to their training.

In the development of this unit, we have proposed that the student understand and evaluate the aspects of the problem that we are going to work on, such as anti-personnel mines. For the resolution, you must apply or adapt technological tools in a significant way by applying computer methods to solve the problem. It is important that the student knows how to analyze, organize and represent information abstractly in such a way that in a collaborative way she can create a metal detector together with her classmates.
