ESP32 is the brain behind this art installation
The ESP32 has enabled countless small electronics projects and even some commercial products, thanks to its small size, low price, and wireless capabilities. Many remote sensors, lighting setups and even home automation projects are now running on this trusty little chip. But being relegated to an electronics box controlling a small electrical setup isn’t all these tiny chips can do as [Eirik Brandal] shows us with this unique piece of audio and visual art.
The project is essentially a small automated synthesizer that contains a series of programmed tables that correspond to various musical scales. Any of these can be selected for the instrument to be played. The notes of the scale are mixed with a few random variations, allowing for a completely automated musical instrument. Music generation is also entirely analog, created by certain oscillators, amplifiers, and other filters and effects. The ESP32 also controls a light sculpture that illuminates a series of LEDs while the music is playing.
The art installation itself creates some pretty haunting and spellbinding tunes which are illustrated in the linked video after the break. While it’s not quite the realm of artificial intelligence as it uses pre-programmed models with a bit of mixed luck, it does give us clues to other projects that have used AI to compose new music. .
