This interactive art installation is a study in magnetism | Arduino Blog
Art is inherently subjective and its meaning varies from one person to the next. But many pieces have widespread appeal as they tap into some emotion we all share. Interactive art pieces tend to stimulate our senses of curiosity and wonder. Niklas Roy’s “Visitors Magnet” installation harnesses the mystique of magnetism to provide that wonder.

Tracking sleep quality with embedded ML and the Arduino Nano 33 BLE Sense | Arduino Blog
Ensuring adequate and restful sleep is vital for maintaining good health, as decreases in sleep quality have been proven to cause a whole host of problems. University of Toronto students Zongyan Yao and Xilin Liu recognized this vital aspect to well-being and wanted to build an inexpensive device that could classify the various stages of sleep as well as report the resulting data wirelessly.
Clinical sleep evaluation is performed by taking polysomnograms, which are essentially measurements of brain, heart, respiratory, and other physiological features. Zongyan and Xilin decided on using an Arduino Nano 33 BLE Sense to classify single-channel EEG values with a lightweight machine learning model due to its relatively fast processor and available RAM. Training data for the model was sourced from the Sleep-EDF Expanded Database that contains several hours of sleep telemetry, including EEG, EOG, airflow, and body temperature, although only the EEG data was kept.
