    And I would be very thankful If you cold provide me with any material in order to understand those arduino codes, not for the Project, but for greater understanding. I've been using Arduino for two years but all of the projects I've made were much more simple tan this one, and I've just copied your codes. However there are many functions I don't know, and, despite the comments you've written in them, I don't get to understand all of their parts. Thank you very much

    I've made it, and I've done a research paper for my final year school Project, with a compilation of the history of acoustic levitation, its practical applications, some home experiments, and a comparation of both single and double sided arrays, obviously statig that it was made with your plans and instructions. It would be a pleasure If you wanted to have a look, I'll leave you my e-mail. nadiabrzostowicz@gmail.com

    Hi, thanks for replying. I've tried it with water and nothing happens. Moreover, using DC in the oscilloscope there's no signal from the transducers despite the fact that the multimeter and the oscilloscope show the 25 Vpp in each one of them. All the red lights are on too. I'll try to desolder everything and solder it again with exposed wire. How do I know that the transducers are working? Do they buzz or get hot? What could have happened so that none of them work? Thank you Asier :)

    Yes, sure. I'm trying but the transducers make absolutely no noise. Here are the connections. Thank you

    Hi Asier,I'm having some trouble lately, as, despite having checked all of the conections and having marked the polarity of the transducers with arduino, they do not seem to work at all. I'm using the MSO-A1640H10T, and I feel lost, as I don't know where the mistake might be. I mean, the transducers get 25 Vpp, but they don't levitate anything. Have you got any idea of what might be going wrong?
