the buzzer doesn't respond to the fdti or the power and also the board doesn't respond to the reset button . only the blue and the yellow led are lighting .
What uploader are you using? We have seen a few cases that the Bluetooth connection breaks after a few uploads. The wired programmer should be good.
Pressing the reset button can also fix a few cases.
The connection issues can usually fixed by reconnecting to the port or restarting the computer.
ya all set up but i mean the board itself doesn't respond to any thing same thing with the buzzer
Do you have the right board selected? It should be Arduino Uno.
