LED Brightness Control Using PWM

March 13, 2026

Solving Approach:

How do you plan to solve it?

I will increase the pwm in according timeline and put a delay function behind each of increasement.

Code

/*Paste your code here*/
Loop(){
Analogwrite(led,62.5);
Delay(500);
Analogwrite(led,125);
Delay(500);
Analogwrite(led,187.5);
Delay(500);
Analogwrite(led,187.5);
Delay(250);
Analogwrite(led,125);
Delay(250);
Analogwrite(led,62.5);
Delay(250);
Analogwrite(led,0);
Delay(250);
}
