#AdafruitLearnSystem Weekly Update

Last week on the Adafruit Learning System, we published 8 new guides. This weeks guides included a light up top hat, a Halloween special giant tombstone with an embedded Adafruit Matrix Display, an LED neon selfie spot, a face mask efficacy tester, and two new QT Py projects! Brent published this great new guide showing us how to build an internet connected air quality monitor using the PM2.5 air quality sensor, and the popular BME280 temperature, humidity, and pressure sensor. He then ties it all together by showing us how to view and log the data using Adafruit IO. This is a great project that shows just how easy it is to build an Internet of Things (IoT) device.
