Sketch: #4

Publish temp and humidity info to rest endpoint w/ basic auth using a base64Encoded string.

I need to work on the formatting of the code block, but the base is there for now.

//Libraries
#include <DHT.h>

//Constants
#define DHTPIN 7     // what pin we're connected to
#define DHTTYPE DHT22   // DHT 22  (AM2302)
DHT dht(DHTPIN, DHTTYPE); //// Initialize DHT sensor for normal 16mhz Arduino
#include <SPI.h>
#include <Ethernet.h>



//Variables
int chk;
float hum;  //Stores humidity value
float temp; //Stores temperature value
float fahrenheit; //Stores fahrenheit temp

int current_count = 9000;   //set counter high to force an initial run.
//int max_count = 60 * 2;    //sleeping for about 2 minutes
float max_count = 60 * 60;    //sleeping for about 2 minutes

// assign a MAC address for the ethernet controller.
// fill in your address here:
byte mac[] = {
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};
// Set the static IP address to use if the DHCP fails to assign
IPAddress ip(192, 168, 0, 177);
IPAddress myDns(192, 168, 0, 1);

// initialize the library instance:
EthernetClient client;

char get_ip_from_this_server[] = "checkip.dyndns.com"; // test web page server

//PROD
//char server[] = "138.197.230.242";  // also change the Host line in httpRequest()

unsigned long lastConnectionTime = 0;           // last time you connected to the server, in milliseconds
const unsigned long postingInterval = 10 * 1000;  // delay between updates, in milliseconds

  // start serial port:
  Serial.begin(9600);
  dht.begin();
  
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // start the Ethernet connection:
  Serial.println("Initialize Ethernet with DHCP:");
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // Check for Ethernet hardware present
    if (Ethernet.hardwareStatus() == EthernetNoHardware) {
      Serial.println("Ethernet shield was not found.  Sorry, can't run without hardware. :(");
      while (true) {
        delay(1); // do nothing, no point running without Ethernet hardware
      }
    }
    if (Ethernet.linkStatus() == LinkOFF) {
      Serial.println("Ethernet cable is not connected.");
    }
    // try to congifure using IP address instead of DHCP:
    Ethernet.begin(mac, ip, myDns);
    Serial.print("My IP address: ");
    Serial.println(Ethernet.localIP());
  } else {
    Serial.print("  DHCP assigned IP ");
    Serial.println(Ethernet.localIP());
  }
  // give the Ethernet shield a second to initialize:
