Create vector video art with an Arduino | Arduino Blog
Unless you’re very young, then you probably remember watching a CRT (cathode-ray tube) television. Those work by directing an electron beam very quickly along row after row while pulsing power to create raster images. But it is also possible to create vector images by directing the electron beam along paths instead of scanning, which you might notice is what an oscilloscope does. Trevor combined these two ideas and made a video explaining how you can create vector video art with an Arduino, a handful of resistors, and an oscilloscope.

The Smart-Badge recognizes kitchen activities with its suite of sensors | Arduino Blog
We all strive to maintain healthier lifestyles, yet the kitchen is often the most challenging environment by far due to it containing a wide range of foods and beverages. The Smart-Badge project, created by a team of researchers from the German Research Centre for Artificial Intelligence (DFKI), aims to track just how many times we reach for the refrigerator door or drink water using machine learning and a suite of environmental sensors.
The wearable device itself is comprised of a single PCB that houses a pair of microcontrollers, an NXP iMXRT1062 for quickly gathering complex data, and an Arduino Nano 33 BLE Sense for collecting more basic samples. Whether it’s the digital gas sensor, the accelerometer, an IR thermal array, or an air pressure sensor, each reading is compiled into a single stream which updates at 6Hz and can either be stored locally on an SD card or sent via Bluetooth® to a phone.
