I have tried many times the uploading of Firmware but getting error all the time.
I have also changed arduino but this did not work.
I think the error messages are pretty self explanatory. By the way you don't need to view them on the command line, you can just scroll up the black console window at the bottom of the Arduino IDE window and you'll see them all, seems more convenient to me that way.
If you want further help screenshots are not going to cut it we need the code and full error output AS TEXT. Screenshots are almost never appropriate here and using them will make it much less likely for you to get help with your problem.
Please post your full sketch. If possible you should always post code directly in the forum thread as text using code tags (</> button on the toolbar). This will make it easy for anyone to look at it, which will increase the likelihood of you getting help. If the sketch is longer than the forum will allow then it's ok to add it as an attachment.
When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error messages in a reply here using code tags.
