Can not upload to Uno R3. Get avrdude: STK500 expect=0x14 resp=0x41 then several others the same.
Using an old Dell laptop with Windows xp. Using latest version of arduino software.
This is my first attempt at using an arduino so not sure if I have everything set right.
OK! Well I got it to work on another computer running windows 7. Is there a problem with the recent software update and Windows XP? Is it not compatable?
