The Arduino is connected to a laptop over a serial connection and is able to move left and right. To spice things up a little, the team added a 25mA laser diode to the build controlled from a ...

Finally, he puts this knowledge to use by building a laser turret based on a pan-tilt platform. The Arduino-driven turret uses two micro servos controlled with pots to move by degrees in X/Y space.

To that end La Fabrique DIY has built an automated system powered by an Arduino to endlessly toy with the feline in your life.

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

Not only does the Arduino-powered turret pack in a deadly-looking laser but it also plays host to a neat motion sensing feature.

Fans of the awesome and iconic Portal and Portal 2 games created by Valve, who enjoy building Arduino powered devices, might fancy building their very own tracking and talking model Portal turret ...
