Hello,

I am a complete newbie to all of this electronically stuff. I have spent a day trying to connect my computer to the arduino uno board. I am using windows 8, i have turned off my internet security and i can now verify the blink sketch. I have no idea what the below error is referring to after hours of trolling the internet. I tried the loop back test and it failed. The driver appears to be installed correctly and the arduino software can see the COM port 4 when I connect the arduino pcb.Has anyone any ideas on what I need to do next?

Using Port : COM4
Using Programmer : arduino
Overriding Baud Rate : 115200

avrdude done. Thank you.

Many thanks in advance! :slight_smile:

That is puzzling. It could be that you got a bad board. Can you upload a screen shot of what you see in device manager for that com port? And photo of your Uno board?

Hi, Please find attached photo's of Uno board and of my device manager screen com port

Thanks for your help.

I not sure what the problem was, but all is well. It's seems to have fixed itself.

Hopefully it will stay that way..!

Thanks again!

Back again.... :frowning:

everything seemed to work fine and now all I get is the below error message. I am able to compile sketches and then when I try and upload it starts by saying 'uploading' then all I get is the below.

Anyone any thoughts? :confused:

Intermittent problem like that makes me think about loose connections, such as the connection between the USB socket and the printed circuit. Or worn out USB port, try a different port on the computer. Or bad USB cable. USB cable is easy to change first. If possible, see how the board works with a different cable and different computer. In the IDE preferences you can check show verbose output during upload, and it may show you more info about the failure.

occasionally I also have issues with upload and the message seems to be similar. Changing USB ports helps. But sometimes after I plug it into a different USB port and it still doesn't upload, then I plug it back into original USB port and it works again :slight_smile:
