Howdy, First off I am new to Arduino and still learning, Sorry if this is a silly question 
ok I have a tft display and I am using the UTFT.H Library. I can display text by using
myGLCD.print("www.arduinoprojectshq.com", CENTER, 227);
But I am trying to work out how to display a variable, I know it is probably easy but any help would be great.

Search UTFT documentation, there is one command like printNum( or similar to do that.
Cool thanks for that .. I found the Doco, I got it working.
int num = 3000;
myGLCD.printNumI(num, 10, 20);
Next Question
Lets Say I have a ODB2 Shield connected to my car and everything setup, All i need to do now is display the RPM value in real time, For testing purposes would this be the best way of doing so ?
void loop()
{
if (obd.ReadSensor(PID_RPM, rpm_value)) {
myGLCD.printNumI(rpm_value, 10, 20);
}
}
Yup. But only update the value if value changed. Also clear the zone, for example if you write "10" then "5" you need to append a " " space to clear the old number
Great thanks for that, I have found myGLCD.clrScr(); but that clears the screen. do you know how i can clear the zone ?

print " "
