"Hello, I have a arduino code to decode my remote control but then I can not send them. Do you know a way ...             Thank you"

Use Ken Sheriff's library.

The adafruit website lists that any wallwart adapter from 5v to 12v will do and also the USB socket can be used to charge ,so both of these 2 different options makes us looking at a minimum voltage threshold of 4.5 to 5.5vdc (depends on pc to pc hardware on usb output voltage) meaning that the board works with at least a minimum of 5vdc input to charge the single cell lipos.

Well try on its good for your academic development OR else there are folks who can do this!

That's good ,have fun with it!

Android commander is also one of those

hmm..... with the code now in view I think surferTim is correct ,you need to close the socket when you are done with the communication .

and.. get your comments right!

Can I use my own bluetooth module on a protoboard & connect that to UNO? Can't see any mention of a wiring schematic.

Yes you can use your bluetooth module on a protoboard and connect that to the UNO ,offcourse your blue module needs to support your protoboard by using a breakout board.

The wiring depends on what your bluetooth modules communication methodology is?

some how a timer counter is adding off bounds and not overflowing getting chip hung.
Please post code also. the latest code.

What problems you are encountering now? Still the freezing?

ahhhhhh, i have done the most newbie mistake in the world smiley
i've assumed the pin7 was a pwm pin. Accordingly to the Mini description, the pwm pins are: 3, 5, 6, 9, 10, 11

You learned a lesson here that first all make sure hardware connections and addressal in code are all correct and then comes the fuses etc lower level setup stuff for your uC and then comes your logic in your code.

use a rotary encoder or quadrature encoder:

see the polulu website for this.

Well you can measure speed using many other available ways.
The thing is which objects speed you wanted to measure?

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:
http://www.dfrobot.com/wiki/index.php/Triple_Axis_Accelerometer_MMA7361_%28SKU:_DFR0143%29#Sample_Code

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 .
