Duet

It’s May, which means that the flowers are in bloom, the trees are budding green, and YouTube and Vimeo are soon to be flush with Arduino-based final art projects. It’s a great time of year! Speaking of art installations…

Duet is a sound and light installation that transforms two set of texts from different source to different pitch, tone and light. We use WWW as the text source. Two different URLs can be input and the Processing will extract the sentences in the web page lively. While the data is transfered from Processing to the Arduino board, different pattern of blinking light and sound are generated. People can get different outcome not only by inputting different URLs, outcome could be different over time as texts are extracted lively from the WWW. And we use U.S. and Hong Kong Google news as demo.

There are five LED light bulbs on the left, representing the first text source, and five on the right representing the second source. The light bulbs are not blinking randomly but they turn on and off according to the length of the sentence that is currently extracted and displayed on the screen. It works the same as the tone of the sound, the longer the length of the sentence, the higher the pitch emitted. From the final outcome of the work, we found that two different sound source, which are both outputting at the same time, sometimes would create a certain level of resonance. In addition to the visual effect from the blinking light, we believe that audience could enjoy with the Duet of WWW.

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.
