One the most creative community members has been creating a lot of Gadgeteer modules and offering them for sale on our creations section. That latest creation is a Bluetooth 4.0 module His entry included this video of a Windows 8 tablet controlling an multicolor LED.
The second video was recently added demonstrating how to use the tilt sensor on a windows 8 tablet to wirelessly control a robot, FEZ Cerbot in this example. Thanks to Gadgeteer, all this hardware design is done without the need for soldering.
