I wanna get an accelerometer for my bot. They can be had extremely cheap on ebay and dealextreme for example, with free shipping, so I'm gonna go for it, even though having stuff shipped here tends to be an experience equally pleasant to getting kicked in the nuts :/ But with the…

Make sure the module you get Make sure the module you get accepts 5V as the power, those IC normally work on 3.3V and the module has to include a small voltage regulator (or, if you can have your own 3.3V power source, you can just use that). Looking at the photos, they all seem…

Thanks guys.Sounds really Thanks guys. Sounds really cool about the MPU6050 I must say, even though it uses I2C for communication (which I have heard can be a mess) and may requiere a separate Arduino just to control it. But does it actually have a complete gyroscope too, or jus…

Well I’m still looking Well I’m still looking forward to the day I can actually read those datasheets. “signal conditioned voltage outputs”, “10,000 g shock survival”, “BW adjustment with a single capacitor per axis”, “RoHS/WEEE lead-free compliant”, etc… Sure that sounds … erm …

Well, the trick is to ignore Well, the trick is to ignore most of the datasheet and only look at the things you actually need. Like the “Operating Voltages”, “Normal Operating Current” (and maybe “Output Leakage Current” if you are going to do funny things with the signal filter…

"It will work right out of "It will work right out of the box…" Thanks for clearing that up. Still I get the idea that it isn’t the easiest module to use. For starters it’s I2C, and Duane also said “I think the code for the MPU6050 is pretty involve…”, so I do expect to have to …

mpu6050 Is there a prefered “better” location to mount these devices?

I have it mounted to the I have it mounted to the base, right in the geometrical center of the robot. Mounting it to the side would make it more difficult to calculate the actual tilt of the robot. I’ve seen some (wheeled) robots that have it mounted on top of a long pole sticki…

mpu6050 position I am a complete novice with this device. Have one and ordered 5 more last night after chasing down eBay prices. The angular velocity should be independent of distance from the axle but the changes in x,y,z should be much greater the further away from the center …

Accelerometer.. Which to buy?

GY-61 is ADXL335, on a small

GY-61 is ADXL335, on a small board, with added voltage regulator. But it’s the same thing.

MPU6050 does have a 3 axis accelerometer and a 3 axis gyroscope, plus a programmable chip that can mix their output or generate interrupts on alarms, etc. – but programming it is an advanced topic. In case of doubt, always check the datasheet:
