- Pachube sensor client
-
- This sketch connects an analog sensor to Pachube (http://www.pachube.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 Pachube.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
-
- created 15 March 2010
- modified 9 Apr 2012
- by Tom Igoe with input from Usman Haque and Joe Saavedra
