Traffic Light with Arduino
This code simulates a traffic light using an Arduino.
int led_rojo = 3;
int led_verde = 4;
int led_amarillo = 5;
void setup() {
pinMode(led_rojo, OUTPUT); // PIN 3 as output
pinMode(led_verde, OUTPUT); // PIN 4 as output
pinMode(led_amarillo, OUTPUT); // PIN 5 as output
}
void loop() {
digitalWrite(led_verde, HIGH); // Turn on green LED
delay(2000);
digitalWrite(led_verde, LOW); // Turn off green LED
delay(500);
digitalWrite(led_amarillo, HIGH); // Turn on yellow LED
delay(2000);
digitalWrite(led_amarillo, LOW); // Turn off yellow LED
delay(500);
digitalWrite(led_rojo, HIGH); // Turn on red LED
delay(2000);
digitalWrite(led_rojo, LOW); // Turn off red LED
delay(500);
