Glowing Air-Bubble Clock in Water

By Marco Ventimiglia on February 27, 2022

In this project we will see how a clock was created that displays the numbers through air bubbles inside tubes.

The system consists of an ESP8266 which, through an I / O Expander MC2301, controls the solenoids that allow the creation of air bubbles inside 8 tubes. There are also a 0.91 “display and 8 NeoPixel positioned at the bottom.
