 We will gradually increment the PWM's duty cycle to increase the brightness, then we gradually decrement the PWM duty cycle to  reduce the brightness of the LED. This effectively creates the dimming LED effect.

+Now, here's the cool part: when this switching happens super quickly, our eyes can't keep up. Instead of seeing the blinking, it just looks like the brightness changes! The longer the LED stays ON, the brighter it seems, and the shorter it's ON, the dimmer it looks. It's like tricking your brain into thinking the LED is smoothly dimming or brightening.
