For fun and a legal form of target practice, Arduino forum member "kaysik" has created an interesting laser target-shooting game based around the Arduino platform. The "gun" consists of a laser pointer, and there are four targets, each raised and lowered by a servo. At the centre of each target is a light-dependent resistor which is ideal for detecting a "strike" by the laser beam. The Arduino sketch can generate random or other patterns of target appearance, giving the players variety of practice in both accuracy and reflexes, as shown in the following video:
Remember, if you're experimenting with laser pointers be careful not to shine the beam into any eyes. Otherwise that's a lot of fun, and for more information and discussion visit the Arduino forum. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
