Hi guys, I’ve searched in the forum for the solution but no-one worked for me. My arduino uno R3 does not work: when I attach it to Mac and try to upload some sketch (also blink sketc) I have the error in the subject. The RX led blink but the L led is always on..
The port and the shield are correct in the IDE...
Do you have any solution?
Try to keep pressed the reset button does not work..
