Why Does an LED Fade Smoothly? 🤯 The Secret of PWM!
In this video you would get to know how PWM actually works? PWM is actually a way to make digital signal behave like analog signal.
We’ll use a potentiometer to adjust LED brightness smoothly.

You can notice some delay while LED changes its brightness, this is because most of the potentiometers can't exactly map the brightness values to the LED. You can try running the program in you arduino, the brightness would change smoothly.

Code for PWM:

#define led 7
#define pot A5

int pot_value = 0;
int led_value = 0;

void setup() {
Serial.begin(9600);
pinMode(led, OUTPUT);
}

void loop() {
pot_value = analogRead(pot);

led_value = map(pot_value, 0, 1023, 0, 255);

analogWrite(led, led_value);

Serial.print("potentiometer: ");
Serial.print(pot_value);
Serial.print(" LED brightness: ");
Serial.println(led_value);
}

📌 What you’ll learn in this video:
1. What PWM is ?
2. Circuit Simulation of PWM signal
3. A hands-on project: controlling LED brightness with a potentiometer
