Explain how this code works in Arduino and construct a circuit for it
//variables
int YELLOW = 3;
int RED = 4;
int DELAY_YELLOW = 1000;
int DELAY_RED = 1000;
// basic functions
void setup()
{
pinMode(YELLOW, OUTPUT);
pinMode(RED, OUTPUT);
}
void loop()
{
yellow_light();
delay(DELAY_YELLOW);
red_light();
delay(DELAY_RED);
}
void yellow_light()
{
digitalWrite(YELLOW, HIGH);
digitalWrite(RED, LOW);
}
void red_light()
{
digitalWrite(YELLOW, LOW);
digitalWrite(RED, HIGH);
}
