-Arduino board
-LED
-Potentiometer

Simply connect the longer leg of your LED to pin 5 of your Arduino and the short leg to GND, connect the potentiometer to GND and +5V and the ADJ to any analog pin on your Arduino board.

Step 1: Code

int led=5;

const int hold=10;

void setup() {

Serial.begin(9600);

// put your setup code here, to run once:

}

void loop()

{

int value=analogRead(A5);

value=map(value,0,1023,0,255);

if(A5 > hold)

{

analogWrite(led, value);

Serial.println(value);

delay(10);

}

// put your main code here, to run repeatedly:

}

Step 2:
