A standard electret microphone can detect sub-audio "sounds" when some simple equalization circuitry is added.

Keep in mind that for both the transmitter and receiver the connections with the Arduino are the same. You can also make connections with the help of the image given below. Connect the data pin of the ...

Not so, if you use a pair of specialised ultrasonic transducer arrays to move the air instead! (Video, embedded below) Three banks of thrusters provide a 180 degree steerable net force Details are ...

To achieve maximum spectral isolation and confinement, we propose a unique zero-energy topological lattice circuit that combines chiral symmetry ... a promising innovation path for the future sensor ...
