System for drawing curve based on Arduino intelligent sound collection

Abstract

The invention relates to a system for specifically displaying and drawing a curve based on Arduino intelligent sound collection. The system comprises a base, a bus servo steering engine, a bracket, acurve drawing pen, a turntable, a microphone, an Arduino single-chip microcomputer, a motor and a power supply device. The power supply device supplies power to the Arduino single-chip microcomputer,the motor, the microphone and the bus servo steering engine, wherein the turntable is mounted on the upper surface of the base, and the motor can drive the turntable to rotate around a central shaft;the bus servo steering engine comprises a main steering wheel, one end of the bracket is connected with the main steering wheel, the other end of the bracket is connected with the curve drawing pen, and the curve drawing pen is located above the rotary disc; the microphone is electrically connected with the Arduino single-chip microcomputer; the Arduino single-chip microcomputer controls the bus servo steering engine to swing left and right according to the sound frequency collected by the microphone, the left and right swing is transmitted to the curve drawing pen through the support, and meanwhile the motor is controlled to drive the rotary disc to rotate around the center axis, so that the curve drawing pen draws a curve related to the sound frequency on the rotary disc.

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.
