Acoustic DIY Making Science Experiment Mini Ultrasonic Suspended for Kids

Description:

PRODUCT: This is a mini device that can suspend foam balls. The device consists of a single chip microcomputer, a chip and two probes.

DESIGN: Small and appearance. Small size, does not take up space.

WORKING PRINCIPLE: standing is that there is a certain distance between the transmitting end and the reflecting end (or another transmitting end) (called the resonant cavity distance), and the transmitted and the reflected (or another acoustic ) are continuously superimposed to form a standing . , the acoustic force on the object at the standing node overcomes the effect of and finally achieves the effect of .

USAGE: is convenient, Micro USB 5V . out two buttons, and write the pins and provide the schematic diagram, and enthusiasts can debug the program by themselves to learn.

APPLICABLE: Mainly used for students or enthusiasts to learn about standing . Controlling the up and down movement of suspended objects is not currenctly supported. Provide source
