Curve drawing system based on arduino intelligent sound collection

Abstract

The invention relates to a specific display and curve drawing system based on Arduino intelligent sound collection, comprising a base, a bus servo steering gear, a bracket, a curve drawing pen, a turntable, a microphone, an Arduino single-chip microcomputer, a motor and a power supply device. Described power supply device provides power supply for Arduino single-chip microcomputer, motor, microphone and bus servo steering gear; Described turntable is installed on the upper surface of base, and described motor can drive described turntable to rotate with central axis; Described The bus servo steering gear includes a main steering wheel, one end of the support is connected to the main steering wheel, and the other end of the support is connected to a drawing curve pen, and the drawing curve pen is located above the turntable; the microphone is electrically connected with the Arduino single-chip electromechanical; the Arduino single-chip microcomputer is based on The sound frequency collected by the microphone controls the left and right swings of the bus servo servo, and transmits the left and right swings to the drawing curve pen through the bracket, and at the same time controls the motor to drive the turntable to rotate on the central axis, so that the drawing curve pen draws on the turntable with the sound frequency related curves.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to an Arduino-based intelligent sound collection system for displaying and drawing curves. Background technique [0002] Noise refers to the sound produced when the sounding body vibrates irregularly. Sound is produced by the vibration of objects and propagates in a certain medium (such as solid, liquid, gas) in the form of waves. From a physiological point of view, all sounds that interfere with people's rest, study and work, and interfere with the sounds they want to hear, that is, unwanted sounds, are collectively referred to as noise. Noise pollution is formed when noise has adverse effects on people and the surrounding environment. Noise can not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, and also interfere with people's life and work. [0003] In order to reduce the impact of noise on the surrounding environment and huma...

Problems solved by technology

[0004] In the prior art, the concrete sound collection devices all need an electronic screen to display the current decibel value, and cannot see the inner performance of the sound more realistically. There are no power components, no sound curve display system, and no target positioning.
