Connect your Arduino-compatible to the Internet with this WiFi shield that features the FCC-certified ATWINC1500 module from Atmel. This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with SSL support and rock solid performance - running our adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it).
Build and code a radio communication system that notifies you of incoming messages, for example via automated puppet, and then displays the message on the Micro:Bit LED screen. No prior experience coding or using hardware is necessary. But! As this project involves communication (a two-way street), it’s a project for two or more people. Grab a friend, a micro:bit each, and build it together! Yayy collaboration! :D
The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows you to flash firmware to the device directly from the command-line using the on-board USB Serial converter and the 'newtmgr' tool, so you can get started right away with no additional hardware required. For more advanced debugging, however, you can use a Segger J-Link and the on-board SWD debug connector, which gives you access to a more powerful set of development tools and options.
Aww yeah, it's the Feather you have been waiting for! The HUZZAH32 is our ESP32-based Feather, made with the official WROOM32 module. We packed everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and all the GPIO brought out so you can use it with any of our Feather Wings.
Using 900Mhz (or 425Mhz) RF for long-range communications between the transmitter and the receivers, this general purpose controller will make your wireless triggering wishes come true! Plus, you get to use a rotary encoder knob to scroll menu sets, and punch in your commands on the lighted 4x4 Trellis keypad.
If you've already got an Amazon Alexa or Echo dot in your home or office, you can easily add your very own devices. In this quick project we'll show how to use an Adafruit ESP8266 Feather HUZZAH to control NeoPixels or a relay. You can easily adapt the code to add any number of devices to a single Feather for all sorts of interactive home automation projects with ease!
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.
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!
