Description
In this project we will work with force-sensitive pressure sensors to generate an alarm that warns us visually and acoustically of the manipulation of a figure displayed in a showcase. The figures will be illuminated with a white light. If they are tampered with, the color of the light changes to red and an alarm sounds. Even if we put the figure back in place, the color of the light does not change and the alarm continues to sound to find out which figure has been tampered with. Let us first explain what a force-dependent sensor is.
The following products of the project are included in the bundle:
-Microcontroller board AZ-ATmega328 board
