Code

Display

C/C++
This is the code for the 16 pin display
#include "application.h"

/*
  LiquidCrystal Library 
  The circuit:
 * LCD RS pin to digital pin D0
 * LCD EN pin to digital pin D1
 * LCD D4 pin to digital pin D2
 * LCD D5 pin to digital pin D3
 * LCD D6 pin to digital pin D4
 * LCD D7 pin to digital pin D5
 * 10K resistor:
 * ends to +5V and ground
 * wiper to LCD VO pin (pin 3)
 * connect R/W (pin 5) to ground

temperature sensor

C/C++
This is the code that collects and converts temperature data, as well as recording it to google docs with IFTTT.
int analogvalue = 0;
double temp = 0;
int tims = 0;
void setup()
{
  Particle.variable("analogvalue", analogvalue);
  Particle.variable("temp", temp);
  Particle.variable("time", tims);

  pinMode(A0, INPUT);
  tims = 0;
}

void loop()
{ delay(1500);
  // Read the analog value of the sensor (TMP36)
  analogvalue = analogRead(A0);
  //Convert the reading into degree 
  temp = (analogvalue*-.08099688473520249+151.99688473520249); //To be accurate
  //temp = 69;
Particle.publish("TempIOT042", String(temp), ALL_DEVICES);
  delay(1000);
temp = 0;
tims = tits + 1000;
if(tims > 5000)
{
    tims = 0;
}


Particle.subscribe("TempIOT042b", String(temp), ALL_DEVICES);


}

void 2waycomm(const char *event, const char *data )
{
    String pew = data;
    temperature = pew.toInt();
}
