Acoustic Levitation
This is an at home/personal project that peeked my interest. I saw an idea for this online and wanted to try to recreate the same result. Below are the ideas and information I have found and used to make this device my own.
circuit diagram
Provided is the first circuit diagram made for the first tests and set up. The connections are as follows:
-out1&2 to both ultrasonic sensors
-ground screw to 9v battery & Arduino nano ground
-9v positive lead to 12v screw
-5v screw to 5v Arduino 5v input
-A0 Arduino output to in1 input
-A1 Arduino output to in2 input
nEXT STEPS
Having the first steps done, its time for improvements. My plan is to take the existing schematic and have it grow. more ultrasonic sensors and more voltage. Currently I am working on wiring the sensors to one another, but the tricky part is finding the right component to amp up the voltage from 9[V] to the required. As I have not finished the final design as of now, the required voltage has not been obtained, but will be soon.
physical testing
This is the design posted on a breadboard. It serves the basic function of working, but a final design is still in the works. I have not been able to find anything I personally like and would like to use, but sketches have been made. You can see the test set up I use and in the second slide you can see a physical piece of Styrofoam being suspended mid air.
3D cad design
Here is the 3D design i had printed out to hold the ultrasonic sensors and wire connections that came with it. The first picture shows how the sensors are positioned. They are positioned in a bowl structure to allow them to essentially face one point in space. The next two pictures show the wiring of the sensors. the red wires show the receivers and the pink are for the emitters.
Inspiration
Clicking the picture you will find the website that got me started with this project. It has a lot of good information and schematics on how to build this and how it works.
first steps
My first steps to creating this was to understand the components used to make this device function. I decided to use an Arduino nano, L298N motor driver, and ultrasonic receivers/transmitters found online.
what is it
Acoustic Levitation is the use of a receiver and transmitter, producing ultrasonic soundwaves. These sound waves act with the principle of force; meaning the force produced upward is the same downward, thus creating suspension.
Gathering code
Using the Arduino Nano for the brain of the project, code had to be written, and with a little online help it was up and running. The code allows for the connection of the Arduino and motor driver to turn on the ultrasonic devices.
