How to use PWM

Cliff W. OP #6773090 
I am using an Arduino Uno, Stone TFT LCD, and F5LED and I want the LED 
to get brighter and brighter as the number increases when I tap the "+" 
on the screen and conversely get dimmer and dimmer. I've tried using PWM 
but it doesn't seem to work. How do I change my code?

Delete everything, learn some basic programming techniques, start over.

PWM_DUTY is not changed, not used, and the analogWrites receive only 
values from 0..255, not 0..1023.

Pulse Width Modulation (PWM) is a fancy term for describing a type of 
digital signal. Pulse width modulation is used in a variety of 
applications including sophisticated control circuitry. A common way we 
use them here at SparkFun is to control dimming of RGB LEDs or to 
control the direction of a servo.
