NI$HANT:

I'm using a triple axis accelerometer, but i don't understand how with these information (X, Y , Z) can i have a speed (m/s).
Here it's the wiki page of the product:
Triple_Axis_Accelerometer_MMA7361_(SKU__DFR0143)-DFRobot

You cannot find the speed using the accelerometer right now, I wanted to do the same sometime back but due to the working physics of an Acc.. involved it wasn't possible .

Ok, thanks for your quick answer, so my microcontroller is useless ? x)
I thought using it just for have a speed...
