Triggers

Use triggers in AdafruitIO to control and react to your data. Configure triggers to email you when your system goes offline, react to a temperature sensor getting too hot, and publish a message to a new feed.

Feeds

Feeds are the core of the Adafruit IO system. The feed holds metadata about the data you push to Adafruit IO. This includes settings for whether the data is public or private, what license the stored sensor data falls under, and a general description of the data. The feed also contains the sensor data values that get pushed to Adafruit IO from your device.

You will need to create one feed for each unique source of data you send to the system. For example, if you have a project with one temperature sensor and two humidity sensors, you would need to create three feeds. One feed for the temperature sensor, and one feed for each humidity sensor.

Integration with IFTTT and Zapier

Want to make your project react to an email, display trending tweets, or turn on the front lights when your pizza is on the way? We baked in integrations with IFTTT and Zapier to connect your project’s sensors to hundreds of web services.

Adafruit IO Arduino Library

This library provides a simple device independent interface for interacting with Adafruit IO using Arduino. It allows you to switch beween WiFi (ESP8266, M0 WINC1500, & WICED), Cellular (32u4 FONA), and Ethernet (Ethernet FeatherWing) with only a two line change in your sketch.

Usage

The included examples sketches will walk you through all of the features of the library. They can be used on all platforms, but they default to WiFi. Most of the sketches have companion projects on the Adafruit Learning system.

To change between platforms, you will need to change two lines of code in the config.h tab of the example. It is recommended that you start with one of the Adafruit WiFi feathers before moving on to cellular or ethernet.

For all examples, you will need to set IO_USERNAME and IO_KEY in the config.h tab:

To find your IO_USERNAME, navigate to your profile on Adafruit IO and click View AIO Key. Copy the Username field (ctrl+c or command+c)

Then, in the config.h tab, replace the "your_username" text with your the username from your profile:

#include "AdafruitIO_WiFi.h"
AdafruitIO_WiFi io(IO_USERNAME, IO_KEY, WIFI_SSID, WIFI_PASS);

#include "AdafruitIO_Ethernet.h"
AdafruitIO_Ethernet io(IO_USERNAME, IO_KEY);

#include "AdafruitIO_WiFi.h"
AdafruitIO_WiFi io(IO_USERNAME, IO_KEY, WIFI_SSID, WIFI_PASS);

#include "AdafruitIO_FONA.h"
AdafruitIO_FONA io(IO_USERNAME, IO_KEY);

void setup() {
  // start the serial connection
  Serial.begin(115200);
  // connect to io.adafruit.com
  io.connect();
  io.setAPN(F("your_apn"), F("your_apn_user"), F("your_apn_pass"));
}
