Thanks

I have done what you have suggested and it work.

Once the script pass, I have program other arduino card and I didn't have the problem.

From what I'm reading in the error message, you computer has trouble communicating with the Arduino.
It looks like your board is a Leonardo? (at first I thought it was a clone, so I had to Google it)

It seems that upload issues like yours are not uncommon for the Leonardo boards.

I did find this in the Leonardo documentation:

Press and hold the reset button on the Leonardo or Micro, then hit the upload button in the Arduino software.
Only release the reset button after you see the message "Uploading..." appear in the software's status bar. When you do so, the bootloader will start, creating a new virtual (CDC) serial port on the computer.

The software will see that port appear and perform the upload using it.
Again, this is only necessary if the normal upload process (i.e. just pressing the uploading button) doesn't work.

So, press and hold the reset button on the Leonardo, press upload in the Arduino IDE, and when you see the message "Uploading ..." let go of the reset button.
Quite an odd fix if you ask me ... but maybe it works in your situation.

A few weeks ago, you have made the meteor rain work  and it worked.

I, today I have tried to modify the sript with no succes.

I have verified various forum with no succes.  I sent the script (via email) to my brother and t works on his computor. 

Can you help

The error message that I have is as follo:

Many thanks, it work perfectly

1) You commented out the "leds1", "leds2", etc definition

2) The "void setup()" line was commented out

3) You did not, or not entirely, copy the suggested code

After correcting those point, this compiles just fine - hope this helps 😊
