Connect the S port of the rotating potentiometer electronic block to the A0 end of the Arduino-plate,and use the following program to read its simulation value.Through the simulation value to set the LED brightness.

const int led = 9;           // the pin that the LED is attached to

int brightness = 0;    // how bright the LED is

void setup()  {

  // declare pin 9 to be an output:

  pinMode(led, OUTPUT);

}

void loop()  {

       brightness = analogRead(A0); //use A0 to read the electrical signal

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

    // set the brightness of pin 9:

    analogWrite(led, brightness);                              

}
