Traffic ligths with Arduino

explanation of the project

This is code of my project

• int rojo=2;
• int amarillo=4;
• int verde=7;
• void setup() {
• pinMode(verde,OUTPUT);
• pinMode(amarillo,OUTPUT);
• pinMode(rojo,OUTPUT);
• }
• void loop() {
• digitalWrite(verde,HIGH);
• delay(3000);
• digitalWrite(verde,LOW);
• delay(500);
• digitalWrite(amarillo,HIGH);
• delay(2000);
• digitalWrite(amarillo,LOW);
• delay(500);
• digitalWrite(rojo,HIGH);
• delay(3000);

• digitalWrite(rojo,LOW);
• delay(500);
• }
