Put the command line in the /etc/rc.local file: （'''Default''') vi /etc/rc.local

NOTE: * The install.sh script will make sure this command line is put into the rc.local file, you don't need to do anything.* Please change 'python' to 'python3' if you are using python3.* Please make sure the file path of pwm_fan_control.py is correct.  2.
