| Difficulty: | Easy to Hard | ||||||
| Estimated Time: | Depends on the project | ||||||
| Skills Required: | A brain and a set of eyes! | ||||||
| Parts Required: | An accelerometer and the project of your choosing. | ||||||
| Tools Required: | Various. | ||||||

You probably have heard the term thrown around, but many out there might not know what an Accelerometer does exactly. They are used in a variety of modern machines and gadgets, and a necessity for dynamic balancing in walking robots. Here is a quick tutorial video that we put together, explaining the basics and application of Accelerometers.

Re: Accelerometers
Great Job. You guys really seamed to have upped your production values. One thing though, it would be cool if you posted sample code, and stuff along with the video. I know that is a lot to ask...but still it would be cool.

Re: Accelerometers
Very,very cool guys, Excellent work. But as DB has mentioned, some code along with maybe the tilt connected to a BS2 or Atom pro28 would also be cool, Thanks for your time guys in putting this together for us.

Re: Accelerometers
Thanks DB! This was actually the first time I ever saw it. Jerks, they've been hiding it from me
 The code that you saw in the video though was the standard demo code from Phidgets: http://www.phidgets.com/downloads.php?os_id=1

Re: Accelerometers
I wouldn't mind putting together a demo on how to use an accelerometer with max in a real world situation like getting a mech ready for mech wars...

Re: Accelerometers
Accelerometers measure force not location. It sounds like you want a gyro (which mesures rotation... i.e. if you turn to the left, you turn 90 degrees)
Accelerometers mesure how quickly you start or stop, and measures the force due to gravity. So a gyro can tell if you moved 90 degrees, but can't tell you how quickly. A accelermoter can tell you how fast you are turning, but not how far. Hope this helps. |

Re: Accelerometers
Extremely well put. It is for this reason that an IMU (Intertial Measurement Unit) is your ideal solution in most advanced applications. A 6 axis IMU combines a 3 axis accelerometer and a 3 axis gyro, meaning you can measure the angle and velocity of any change on all 3 axis'.
Great post Eric, + rep. Quote:
