Cosm sensor client
|
||||
|
||||
This sketch connects an analog sensor to Cosm (http://www.cosm.com)
|
||||
using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
|
||||
the Adafruit Ethernet shield, either one will work, as long as it's got
|
||||
a Wiznet Ethernet module on board.
|
||||
|
||||
This example has been updated to use version 2.0 of the cosm.com API.
|
||||
To make it work, create a feed with a datastream, and give it the ID
|
||||
sensor1. Or change the code below to match your feed.
|
||||
|
||||
|
||||
Circuit:
|
||||
* Analog sensor attached to analog in 0
|
||||
* Ethernet shield attached to pins 10, 11, 12, 13

||||
