Accelerometer


Vendor's Description: 


Accelerometers are very exciting little things. When I say "little", I mean it, as they usuallyfits 4 or more on a finger nail! And each typically has some 7-20 points so solder. This makes them quite hard to work with, and so I recomend that you also buy a board of some sort, so that you end up with something that you can hook up to your Microcontroller easily.

What you get from the thing is a signal. The signal can be analouge, I2C, or anything else, depending on the thing you get.

I prefer analouge, it is just SO easy to work with; hook it up to an analoge input, read, you are go :)

So what does it return to your microcontrolelr, then?

Well, inside the tiny box is a liiitle chamber with a gas or something. And around this gas cloud or whatever, there are sensors. The gas is lighter or heavier than air or something (this is very precise info, no? ;) - and  the resoult is that you get info about how the thing is tilted, or moved around in the air.

You can get them with 1, 2, or 3 axis, I have not seen them with 4 yet (joke).

You know them from the Ninendo Wii handles, and you can use them for such things as:

  • Balance
  • Registering drift on fast robots
  • Registering if the robot-pet-animal is lifted up, perhaps shaken by the stupid kid
  • Cool "In Air" joysticks
  • To build something that will tell you how fast your car is accelerating.. or your bike ;)
  • Registering if your Sumo-robot is just getting hit by another
  • Making auto-corecting flying things
  • and much more :)

I got mine here:

I just stumpled upon this place that aprantly sells some nice ones:

I like this component posting stuff. You just saved me a bunch of searching in the future.

THANKS!!

How can I place a accelerometer to my picaxe 28 board??
