Arduino Nokia 5110 LCD temp meter DS18B20

Hello World! I made a Arduino Nokia 5110 LCD Temperature meter with a Nokia 5110 LCD.
I added the librarys and i made a Image for the LCD background with a rounded border and temperature icon which
is added to the LCD5110_Graph Libary and is named borderRoundedIcon.c

Arduino Nokia 5110 LCD DS18B20

Just wire everything up like the schematic and upload the code.

Make sure you download and install the libraries first! You need them!

Put the pins on the LCD like following:
PIN1 on LCD ==>> PIN 12 on Arduino
PIN2 on LCD ==>> PIN 11 on Arduino
PIN3 on LCD ==>> PIN 10 on Arduino
PIN4 on LCD ==>> PIN 9 on Arduino
PIN5 on LCD ==>> PIN 8 on Arduino
PIN6 on LCD ==>> PIN 3.3 Volt on Arduino
PIN7 on LCD ==>> PIN 5 volt on Arduino
PIN8 on LCD ==>> PIN Ground on Arduino

Parts list:
Arduino Uno, I used the robotdyn uno.
DS18b20 Temperature Sensor.
Nokia 5110 LCD
Jumper wires MM/FF/MF.

Arduino Nokia 5110 LCD temp meter.
Hello world! this is a example project for the DS18b20 on a old Nokia 5110 LCD Display.

#include <OneWire.h>
#include <DallasTemperature.h>
#include <LCD5110_Graph.h>
#define ONE_WIRE_BUS 2

LCD5110 lcd(8,9,10,12,11);

extern unsigned char SmallFont[];
extern unsigned char BigNumbers[];
extern uint8_t borderRoundedIcon[];

char TempCelciusFahrenheit[6];

OneWire oneWire(ONE_WIRE_BUS);

DallasTemperature sensors(&oneWire);

float tempC = 0;
float tempF = 0;

void setup(void)

void loop(void)
  lcd.drawBitmap(0, 0, borderRoundedIcon, 84, 48);
  tempC = sensors.getTempCByIndex(0);
  tempF = sensors.toFahrenheit(tempC); 
//  convertToString(tempF); //these are Fahrenheit, uncomment when using degrees.
  convertToString(tempC);  //These are degrees, comment when using Fahrenheit.
  lcd.print(TempCelciusFahrenheit,22,14); // You can set position of the text here.
  lcd.print("Temp.Celc.",17,5); //Comment when using Fahrenheit
//  lcd.print("Temp.Fahr.",17,5); //Uncomment when using Celcius
void convertToString(float number)
   dtostrf(number, 3, 1, TempCelciusFahrenheit);
