Hi i am having a problem with my Arduino Nano:
I can't upload any sketch because there is a problem with the communication.
I am using a Macbook pro, Big Sur 11.4 (I also tried it with a windows PC, same problem)
The Arduino is original and I also bought a second one wich also doesn't work.
I have an Arduino Uno wich works perfectly so i really don't see the problem.
Here the things I already tried:
-using an other usb cable
-using an other Arduino
-other prozessor (old bootloader)
-board and port are also selected
I tried so many things so many times I hope someone can help :slight_smile
This is the error im having:
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
