Arduino and the rest of the Free Hardware projects are reaching the educational world and this shows in the number of projects that are created for the class but that can be applied to any other aspect of daily life.
A clear example of this is the noise meter that a teacher recently created for their classroom and that we can improve it or simply create it to use it at home or in the office, depending on our work.
This noise meter only needs a plate Arduino UNO or any other similar; a noise sensor and a NeoPixel led strip or led panel. Thus, the idea is that the Arduino board captures the noise through the sensor and through an algorithm represents it on the led strip or on the led screen. The new Neopixel led strips are quite useful for certain projects since they allow us to have meters the same as the thermometer, which depending on the intensity, the light advances and changes color.
This noise meter can be customized to make it more attractive to the little ones
We can also do this with led screens that allow us not only to make a graphic representation but also a numerical representation by inserting a scale. This is interesting, but in any case we see how with an Arduino board and a simple sensor we can create a noise meter, something useful for certain aspects or if we want to measure the noise generated by the neighbor at night or the bar below the floor.
In any case, we want it for what we want, the noise meter is a totally free project to which we can get the instructions through this link which is the website of the teacher who has created this project and who has published it on his website, something that is still good to influence and teach new generations of makers Do not you think?
