Go to codebenders.cc and you will be able to sketch, verify and upload to all your boards. I have wasted a month of my short life Cancer. Trying to get the computer to let my Arduino programme work. But not only will the computer fail to Verify and fail to upload. Now Google is Telling me, How DARE! They? That Codebenders is not allowed on my computer! Excuse me, it is Mine and not Googles.
On top of that, now some thing is interfering with Fire Fox private browser. which is how I have been able to get my two Uno's and one Mega 2560 to work. So please folks Tell Google and all browsers that it is safe. Google and Microsoft are killing me by not letting me, make little LED light as a retirement hobby. Stress from interference and aggravation. The point is: If my programming works on my boards via Codebenders and of course the copy and pasted codes from here plus the examples that come with the IDE work also. Why does my computer lie to me and say there is a fault? Why is Google blocking me =( and who is interfering with Firefox and blocking it :0
I had such an over whelming sense of relief of stress that I was nearly crying with happiness when I found codebender and all my sketches worked! and my three boards too. Now I am in deep depression Due to Google and I think Microsoft. I can not sue them but Facebook them to death I may have to.
