I have trouble uploading the StandardFirmata sketch to my Arduino Uno board.
Can somebody help me with the troubleshooting?

It means you have not selected the correct com port from the tools box or your Arduino is not working.

It has nothing to do with what you are trying to upload.

Thanks a lot, problem fixed!
