//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);

}

Based on the previous example add a button as input and modify the program,

As can be seen from the program, the green LED should be lighted ON. Press the button and the yellow LED should light and followed by red LED when pressed again. Add the following new type: Typedef enum {GREEN

Change the parameter to the light_one_led to colors instead of int.

Change the 1, 2, 3, in the call to GREEN, YELLOW, RED
