hey guys so i get this error when plugging in my arduino and not sure why:
Arduino: 1.8.9 (Windows 10), Board: "Arduino/Genuino Uno"
Sketch uses 930 bytes (2%) of program storage space. Maximum is 32256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes. avrdude: ser_open(): can't open device "\.\COM5": The system cannot find the file specified.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.
How can i solve it? It used to work and not sure what's happened... also does anyone know if the Braccio robotic arm can be connected to arduino via just the arduino/usb cable alone? Because when i connect the braccio shield v4 to both th arduino(and to laptop) and to the wall, it actually causes my laptop to switch off ??
