How to solve "avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied"?
When programming microcontroller or Arduino with AVRDUDE (or Arduino IDE) on Linux, if you get the following error, it means AVRDUDE does not have permissions on the USB ports (/dev/ttyUSBx or /dev/ttyACM0).

The best option is to add the current user to the dialout group which owns the device file with the following command:
Restart the computer so that the changes are applied.sudo usermod -a -G dialout $USER
