The Development of Light Refraction Experiment Instrument Based on Arduino Single Chip Microcomputer and 3D Printing Technology

初中物理光学实验主要目的就是让学生掌握光的反射折射规律,目前现有的光反射折射实验器材自动化程度低,不方便实验教学。针对这一现状,本团队研究了一种光反射折射实验仪,首先通过功能需求分析,列出了该实验仪应该具备的功能,确定了其结构和工作原理;其次用Arduino单片机作为该实验仪的控制核心,研究了其控制系统的硬件构成和软件编程;最后利用了3D打印等制作技术,完成了该光反射折射实验仪的制作,并进行测试试验。试验表明,该实验仪能够满足预期的功能和实验教学的需要。

The main purpose of optical experiment in Junior high school physics is to let students master the law of reflection and refraction of light.At present,the automation degree of existing light reflection and refraction experimental equipment is low,which is not convenient for experimental teaching.For this situation,the team studied a light reflection and refraction tester.Firstly,through the functional requirements analysis,we listed the functions that the tester should have,and designed its structure,and determined how it works.Secondly,using arduino single chip microcomputer as the control core of the tester,studied the hardware composition and software programming of its control system.Finally,using 3D printing and other production techniques,manufactured the light reflection and refraction tester,and carried out the test.The experiment shows that the experiment instrument can meet the expected function and the need of experimental teaching.
