Acoustic Levitation With Arduino Uno Step-by Step (8-steps)

Acoustic levitation is a technique that uses high-frequency sound waves to suspend objects in the air without any physical contact. It works by creating a pattern of high and low-pressure zones, forming what’s called a "standing wave." When an object is placed in the low-pressure areas, it stays balanced due to the forces from the sound waves pushing against gravity. This effect can be achieved using ultrasonic waves, which are beyond the range of human hearing. Scientists use this method for ha
