Poonampipaliya,
The task of debugging something that has suddenly stopped working requires breaking up the processing into little blocks that should all work, and then checking all the tasks that should work.
You are using a Gemma. It has on it a Red led (Pin #1). So work your way through the process from easiest to hardest.
Is it plugged into a power supply?
Is the switch on?
Does the Red led blink when you try to load a program onto it?
Can you run a basic blinking code on it?
Then look for things you would not expect. Are any wires broken? Has the reset button gotten loose or is it stuck down?
I assume that you have gotten the LED strips to work at least once before putting the whole system together??
Best Regards,

@POONAMPIPALIYA Please start a new thread for your issue. Photos of your project would also greatly help.

Arduino: 1.8.5 (Windows 7), Board: "Arduino Gemma"
Sketch uses 704 bytes (13%) of program storage space. Maximum is 5310 bytes.
Global variables use 9 bytes of dynamic memory.
avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
this error comes even while uploading the simplest gemma led blinking code.

Re: Help with Tiara Project - Programming the Gemma in Ardui
Are you using an Arduino Gemma or an Adafruit Gemma? They are two different things.

Re: Help with Tiara Project - Programming the Gemma in Ardui
oh yeah!! my blunder. Thanks for pointing it out. It worked. Now, it shows that USBTiny device not found, i have also changed the programmer.

POONAMPIPALIYA - I would post a new thread in the forums, with all the details of your project.
I know that we had to connect our Gemma board to the laptop using a powered USB hub, and have to double check that in the Arduino IDE the correct options are selected for Board and Programmer.

Re: Help with Tiara Project - Programming the Gemma in Ardui
Thanks for these commands is just what I was looking for!Take a look here for a run down of the commands in the NeoPixel library:
https://learn.adafruit.com/adafruit-neopixel-uberguidecanada/arduino-library-use
and then take a look at the various functions in the strandtest example:

Cheers,Binaro.
