Solved avrdude: ser_open(): can't open device Permission denied

 How to Configure Permission Denied Port

When you upload the code to the Arduino board using Linux and get an error appears like this:

avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied

You can fix it with this command in terminal:

1. Modify user accounts.

sudo usermod -a -G dialout <username>

For example, my computer username is neon, then write:

sudo usermod -a -G dialout neon

2. Give permission for ports to be read and written using the terminal with two commands:

sudo chmod a+rw /dev/tty<ACM or USB>

For example, the detected port name is ttyUSB0, then the command is:

sudo chmod a+rw /dev/ttyUSB0

3. Done
