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.
38  Using Arduino / Microcontrollers / Re: [Q][Triple Axis Accelerometer][DFR0143]How to have a speed in m/s with this obj? on: April 03, 2014, 04:45:25 am
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 .

A Deumilanove in my case I use it to programme almost all sorts of ATmega and ATTiny uCs.
42  Using Arduino / Microcontrollers / Re: SLEEPING ATmega328 in my case scenario! on: April 03, 2014, 03:41:42 am
So it seems now to work.

but still it maybecome a bit undependable in case the Interrupt source registers aren't cleared all fine, although I cleared it but ppl seem to have problem of INT1 or INT2 pin being high even when no interrupt is there and also the Source registers are cleared up.

i cannot control each led! I need just one color (RGB) for the entire strip. So i think it's not a memory problem...

I have done a lot of this RGB strip and LED addressal and according to just your narration(even that is like mostly probably you only understand it the best) and no code I came to that ram low point.

Reinitialization won't work.
45  Using Arduino / Microcontrollers / Re: SLEEPING ATmega328 in my case scenario! on: April 03, 2014, 01:33:59 am
I'm using a interrupt from MMA8452Q on pin 3 ,I think may be I'll have to reinitialize the acc. when I wake up, trying that......
