Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I have my Arduino Mega 2560 in COM11 and when I test it to other computers, it is working fine. I have a problem with this even with Arduino Galileo. I think it’s because of the software or I installed it in a wrong way. Help me :(( I need this to solve by this week… I tried to reinstall it but it doesn’t work.

In addition, my codes were like this:

void setup(){
pinMode(13, OUTPUT);
}
void loop(){
digitalWrite(13, HIGH);
delay(300);
digitalWrite(13, LOW);
delay(300);
}

Try an earlier version of the IDE. Using the hourly build is living a bit dangerously.

#3

How? I asked my friend to send his installer yet he hasn’t replied

#4

At the top of this page click "Downloads". Select one of the options for version 1.6.6 in the top box. Stay away from the box below that which says hourly build.

Thank you guys :smiley: It really helped me. I hoped this time it works because I need this done by Monday.

You don't need a friend for this. The previous releases are on the web site:
