This is an Arduino gadget cache on the East side of Naranja City Park. It's a short, steep walk from parking that gives you a great view of the new park. To log a find, all you gotta do is win an electronic shell game to open the container and sign the log.
When you find the cache and open the container, you will be presented with three blinking lights and three buttons. To win a round, you must pick the light which was illumnated last in the sequence. After you win three rounds, the door will unlock for five, yes, that's five seconds. Don't know which light was the last one? Well, just use your best geosense and pick a button to push. Just keep trying and I know you'll come up a winner. Unlike the real shell game, there is no wagering involved!
After you sign the log and replace the cache, look up and enjoy the view of the park. If you're lucky enough, you might see some remote controlled airplanes flying around. But as always, watch your step, wear sun screen, and bring drinking water.
