Proyecto de la escuela en el cual haremos un semáfaro programando las luces leds para que enciendan con una señal del censor.

2 
// Definición de los pines para cada color
const int ledRojo = 2;
const int ledAmarillo = 3;
const int ledVerde = 4;

void setup() {
  // Configuramos los pines como salidas
  pinMode(ledRojo, OUTPUT);
  pinMode(ledAmarillo, OUTPUT);
  pinMode(ledVerde, OUTPUT);
}

void loop() {
  // 1. Encender el LED Verde (3 segundos)
  digitalWrite(ledVerde, HIGH);
  digitalWrite(ledAmarillo, LOW);
  digitalWrite(ledRojo, LOW);
  delay(3000);

  // 2. Encender el LED Amarillo (1 segundo)
  digitalWrite(ledVerde, LOW);
  digitalWrite(ledAmarillo, HIGH);
  digitalWrite(ledRojo, LOW);
  delay(1000);

  // 3. Encender el LED Rojo (3 segundos)
  digitalWrite(ledVerde, LOW);
  digitalWrite(ledAmarillo, LOW);
  digitalWrite(ledRojo, HIGH);
  delay(3000);
}

Your project lacks a sensor.

Add...

const int button = 5; // a sensor - PIN >> BUTTON N.O. >> BUTTON N.O.  >> GND

then in setup()...

  pinMode(button, INPUT_PULLUP); // RELEASED = HIGH, PRESSED = LOW

then in loop() AFTER green HIGH/yellow LOW/red LOW...

  while (digitalRead(button)) {} // wait for button

This will wait for the button to be pressed to cycle yellow, then red, then back to green.
