(Arduino) Problems With UNO READ

Hi!!!

I'm having problems With the "UNO READ": it 's red all the time and no data is collected. I can "Write" and control manually some Leds,  but not through the data collected by my sensors. I have developed an equalizer definition, And I need to control it With a sound sensor.

Even When I change the position of the USB in other sockets, always recognize that I'm using COM 3. Is this normal??

I hope you could help me to make it work, before Friday! It's my project delivery day.

Thanks,

Carlos
