void setup() {
Serial.begin(9600);
pinMode (potPin , INPUT);
pinMode (ledPin , OUTPUT);
}
void loop() {
potValue=analogRead(potPin);
ledValue=map(potValue, 0, 1023, 0, 255);
analogWrite(ledPin, ledValue);
Serial.print("Value of the potentiometer = ");
Serial.println(potValue);
Serial.print("Value of the led = ");
Serial.println(ledValue);
Serial.print ("
");
delay(1000);
}
