Schluff is a Yiddish word which means to take a short nap. This project is about finding the ideal environment for quality sleep by monitoring different conditions and biometric data. Ideally, the data from this device would be overlayed with a wrist-based fitness tracker for additional revelations. Schluff records the following: temperature, humidity, light, noise and heart rate. The collected data is sent from a Feather 32u4 (Arduino compatible) over to an iOS device or macOS laptop using BLE (Bluetooth Low Energy). The BLE catchers can save the data locally or relay it up to adafruit.io for storage and graphing.
In most situations finding the MAC address of a wireless device is fairly straightforward. However, there are some things like smart TVs, IOT devices, gaming consoles, etc. that either don't display that MAC or have it hidden in a mess of on-screen menus. This device broadcasts a wireless network without a password. Connect any wireless device to it and once the connection is made the MAC address of the device will be displayed on the small OLED screen.
Add short-hop wireless to your Feather with these Radio Featherwings. These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x's). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device.
The ESP8266 based Feather HUZZAH & the HUZZAH ESP8266 breakout are both very popular options for connecting projects to Adafruit IO. In this guide we are going to walk through the setup needed to get your ESP8266 up and running with the Arduino IDE & Adafruit IO. This same basic setup can be used as you progress through our Adafruit IO Basics series of guides.
This is the Adafruit Feather M0 RFM69 Packet Radio (433 or 900 MHz) - our take on an microcontroller with a 433 or 868/915 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GHz 802.15.4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi.
Have some fun with the Adafruit Feather HUZZAH and the CheerLight project. Originally created by Hans Scharler, CheerLights allows people’s lights all over the world to synchronize to one color set by a specific Twitter feed. In this interpretation, Marc de Vinck creates a WiFi enable CheerLight using the Adafruit Feather HUZZAH, Neopixels, and some clever code.
For transit-bound people, the NextBus service is a tremendous convenience. Knowing when a bus is due means less standing out in the rain…one can use that time inside to get a little extra work done, or finish that cup of coffee. In this tutorial we'll build a handy desk-top or wall-mount countdown display that lets you know when the next bus or train is on the way!
