Autonomous Light-music Installation powered by Arduino! #Arduino

Via Vtol

This project is an autonomous light-music installation. The main element of the piece is the construction fixed on the wall, with 7 powerful red lasers which send light horizontally. The laser rays pass through several pc fans rotating on high speed, placed along whole length of the installation. The fans serve as dividers-modulators which turn the ray into rhythmic impulses instead of the permanent ray. The frame opposite from the emitters has photo sensors which register the presence or absence of the ray. Thus, the system has 7 independent binary variables which become the basis for creation of sound composition. The speed of the each of fans is variable which leads to constant shift of modulation phases of the light rays.

The central idea of the project “Divider” lies in an abstract artistic interpretation of the wave-particle duality concept that every physical object may be described mathematically in terms of wave quotations, as well as from a formalist point of view that conceives object as a particle or a particle system. As a textbook example of that duality, we can think of light as a particle (photon) flux, which works like an electromagnetic wave in various physical experiments. In the artwork, the rays are interrupted repeatedly and constantly, but not simultaneously – as to create a polyphase source of uncertain events.

The uncertainty relation sets the lower limit for the product of the paired observables standard deviations. The principle of uncertainty discovered by Werner Heisenberg in 1927 is one of the milestones of quantum mechanics, and is a corollary of the wave-particle duality principle. Eventually, the divided and unstable system transforms into a set of binary states, which make light into a discrete message matrix, which, in turn, generates sound waves (a musical composition). Thus, the work attempts to use the experimental language of art to bring up and describe the global issues – is the universe discrete? can we describe the universe with the language of energy, frequency, and vibration – in accordance with the testament of Nikola Tesla?

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
