yesterday i got a little angry , because i got avrdude: stk500_recv(): programmer is not responding , as un error while trying to upload a sketch.
I read different approaches to this Error , and nothing worked for me
The Arduino Uno is recognized by my macbook and i can select the right port in IDE
i tried to hook up an external power supply , some guy had figured out that the USB port was not delivering enough mA to upload a sketch.
tried to Reset the Uno.
I’m out of solutions that i came across , so i thought to give it a shot here
