Hi I am trying to code my 12 pin 7 segment display to display the temperature from my grove temperature sensor. I am new to this and I have been struggling if anyone code help that would be muchly appreciated. I don't have a reputation over 10 so I can't put in images :( My temperature sensor is displaying its information in the serial monitor I want the temperature displayed with the 7 segment display. (Thats where I need help)

//Temperature Variables
//thermistor = value of the thermistor
int a;
float temperature;
int thermistor=3975;
float resistance;
boolean DigitOn = LOW;
boolean DigitOff = HIGH;
boolean SegOn=HIGH;
boolean SegOff=LOW;

int DigitPins[] = {2, 3, 4, 5};
int SegmentPins[] = {6, 7, 8, 9, 10, 11, 12, 13};

//N is for numbers and NxP is a number with a decimal point behind
int BLANK[] = {LOW, LOW, LOW, LOW, LOW, LOW, LOW, LOW};
int N0[]    = {HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, LOW, LOW};
int N0P[]   = {HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, LOW, HIGH};
int N1[]    = {LOW, HIGH, HIGH, LOW, LOW, LOW, LOW, LOW};
int N1P[]   = {LOW, HIGH, HIGH, LOW, LOW, LOW, LOW, HIGH};
int N2[]    = {HIGH, HIGH, LOW, HIGH, HIGH, LOW, HIGH, LOW};
int N2P[]   = {HIGH, HIGH, LOW, HIGH, HIGH, LOW, HIGH, HIGH};
int N3[]    = {HIGH, HIGH, HIGH, HIGH, LOW, LOW, HIGH, LOW};
int N3P[]   = {HIGH, HIGH, HIGH, HIGH, LOW, LOW, HIGH, HIGH};
int N4[]    = {LOW, HIGH, HIGH, LOW, LOW, HIGH, HIGH, LOW};
