Flew sensor and a LED

Hello,
I am new to arduino and coding and i have a question regarding flex sensors. I am trying to make it so that when a flex sensor has a value between 10 and 0, around the straight position, then turn on a LED. And when it is bent, the LED is turned off. I have looked around online and can not figure out how to do this. Can anybody help?
Thanks

if ( analogRead(pinANALOG_FLEX_SENSOR) <= 10 )
{
    digitalWrite(pinLED, LED_ON);
}
else
{
    digitalWrite(pinLED, LED_OFF);
}

^That would be “analogRead”

if ( analogRead(pinANALOG_FLEX_SENSOR) <= 10 )
{
    digitalWrite(pinLED, HIGH);
}
else
{
    digitalWrite(pinLED, LOW);
}

Thank you for wha you have shown me, but how would I set everything up so that the console knows what I mean by analogread and what not.
I am sorry, I am new.

This is untested code. Your flex sensor should be connected to analog pin 0 and the LED to pin 12.

byte pinLED = 12;
byte pinFlex = A0;

void setup() 
{                
    pinMode(pinLED, OUTPUT);     
}

void loop() 
{
    if ( analogRead(pinFlex) <= 10 )
    {
        digitalWrite(pinLED, HIGH);
    }
    else
    {
        digitalWrite(pinLED, LOW);
    }
}

Thank you very much for your help.

Yes, well, I was being rushed out the door ...
