PRÁCTICA:

int led1 = 1;
int led2 = 2;
int led3 = 3;
int led4 = 4;

//
int potenciometro = A0;



int valorPoteciometro;//0-1023 = 1024 estados



void setup() {

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

  pinMode(led1,OUTPUT);
  pinMode(led2,OUTPUT);
  pinMode(led3,OUTPUT);
  pinMode(led4,OUTPUT);

}


void loop() {

  // put your main code here, to run repeatedly:
  digitalWrite(led1,HIGH);
  digitalWrite(led2,HIGH);
  digitalWrite(led3,HIGH);
  digitalWrite(led4,HIGH);


delay(500);


  digitalWrite(led1,LOW);
  digitalWrite(led2,LOW);
  digitalWrite(led3,LOW);
  digitalWrite(led4,LOW);


delay(500);
