If you get a permission denied error when accessing /dev/ttyACM0. You may need to add your user to a linux user group that has access to the serial interface. First, we find the group using:
ls -l /dev/ttyACM0
I get the following output on my machine:
crw-rw---- 1 root uucp 166, 0 Aug 19 03:29 /dev/ttyACM0
To add your username to uucp group, we run:
sudo usermod -a -G uucp $USER
