 Bigger Bigger  Smaller Smaller  Reset Reset

We are some boys doing a project in school, our goal is to build a cube, 8x8x8 with LED-lights.
There is one problem though, when we are ready to lanch the code, we get an error message.
The code is Verifyed and all with no problems.

The error code says:
avrdude: stk500v2_getsync(): can't communicate with device: resp=0x01
avrdude: stk500v2_command(): unknown status 0xc8
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

avrdude: stk500v2_command(): unknown status 0x01
avrdude: stk500v2_disable(): failed to leave programming mode

It doesn't help to double check or use -F to override.

Anyone with any suggestions?

Thanks in advance

You have to tell us more.
Which operating system ?
Which Arduino board ?
Do you use the newest Arduino 1.0.3 ?

You could try with or without USB hub, on another computer, with another Arduino board.

Do you have any wires plugged into the Arduino, apart from the USB cable?
