Sound system
This system is responsible for the controlled vibration of the water droplets. For this reason a speaker is attached at the end of the water pipe. The device uses a 1 W speaker, an electrical circuit acting as an amplifier and an Arduino UNO microcontroller, as shown in the figures below.
