The Arduino uses DHCP and DNS for a simpler network setup. 11 The sketch also includes a Watchdog / Reset function to make sure the 12 Arduino stays connected and/or regains connectivity after a network outage. 13 Use the Serial Monitor on the Arduino IDE to see verbose network feedback 14 and ThingSpeak connectivity status Getting Started with ThingSpeak: * Sign Up for New User Account * Create a new Channel by selecting Channels and then Create New Channel 20 * Enter the Write API Key in this sketch under "ThingSpeak Settings" Arduino Requirements: * Arduino with Ethernet Shield or Arduino Ethernet 25 * Arduino 1.0+ IDE Network Requirements: 28 * Ethernet port on Router 29 * DHCP enabled on Router 30 * Unique MAC Address for Arduino Other Requirements: 33 * BMP-085 Sensor 34 */ #include <SPI.h> 37 #include <Ethernet.h> 38 #include <Client.h> 39 #include <Wire.h> //Including wire library 40 #include <Adafruit_BMP085.h> //Including BMP180 library #define ALTITUDE 256 //Altitude where I live (P'dorf 256 m) 43
