I'm a new user of bot Ubuntu and Arduino and whenever I try to upload a sketch into the board I'm getting this error message:
Arduino: 1.8.9 (Linux), TD: 1.47, Board: "Arduino/Genuino Uno"
Build options changed, rebuilding all
Sketch uses 776 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 "/dev/ttyACM0": Permission denied
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.
Hope any Linux user can help me with this one,
Thanks in advance,
Lucho
