What pins does it use?

I’m tempted to make a mockup using some LEDs. :P

#include "Pokitto.h"

Pokitto::Core mygame;

Ticker LightTimer;
DigitalOut red1(EXT3);

enum LightStates {
    red = 0,
    rednyellow = 1,
    green = 2,
    yellow = 3
};

LightStates lights1,lights2;

void change() {
    switch (lights1) {
    case red:
        lights1 = rednyellow;
        lights2 = yellow;

I had a rug/mat just like that when I was younger. It might have even been the same pattern.

I’ll set up a circuit tomorrow to give it a go (it’ll be easier in daylight).
It won’t be as cool as the real thing, but it’ll be fun at least.
