Example program (UNO development board):

volatile float Voltage;
volatile float data;
volatile int light;

void setup(){
  Serial.begin(9600);
  Voltage = 0;
  data = 0;
  light = 0;
  pinMode(A0, INPUT);
  pinMode(9, OUTPUT);
}

void loop(){
  //电位器接A0；led灯接D9

  data = analogRead(A0);
  Voltage = (data / 978) * 5;
  light = (map(constrain(analogRead(A0), 0, 978), 0, 978, 0, 255));
  Serial.print("Voltage is:");
  Serial.print(Voltage);
  Serial.print("V");
  Serial.print("    light is:");
  Serial.println(light);
  analogWrite(9, light);
  delay(100);
