So let's take a look at this little doodad and see what it's got. There's stuff all over both sides of this thing. Not sure if anyone knows which is the front and which is the back, but here's what's on one side.

Compass? Accelerometer? Bluetooth? Neat.

But the other side may be even cooler. It's got two buttons which are useful. But the really cool thing is the 5 x 5 grid of little LED lights. That's 25 total LEDs. And each one can be turned on and off individually. You can even set the brightness!

Along the bottom edge are a bunch of gold connection pads. The most important of these are the 5 bigs ones - the ones with the big holes. These will allow you to attach all kinds of additional items using alligator style clips. No soldering needed!

Now let's look at all this stuff in more detail. That is, if you want to. If not, go ahead and skip on to the Let's Code section to learn about programming. That's where the fun is at!
