A simple traffic light with only two leds. Un semáforo simple usando solo dos leds.
A simple traffic light for beginers: One red led is connected to de pin#7 and another green led to the pin#4. The red light stays on for 5 seconds, then the light blink and change to green.
This is my second project with Arduino.
