Cron is not Running for my laravel 5 project

This question may be duplicate (CronJob not running) however, it does not resolve my issue. Let me explain this. By seeing the post in https://laravelcode.com/post/laravel-55-task-scheduling-with-cron-job-example , I wanted to set the cronjob via terminal. I see from FTP that artisan has set in the path: /var/www/html/projectName/ and I believe that this server is Ubuntu. I ran this below command but did not happen anything.

* * * * * /var/www/html /var/www/html/projectName/artisan schedule:run 1>> /dev/null 2>&1

From the above mentioned stackoverflow post, I ran the command ps ax | grep cron which return me:

1013 ?        Ss     0:57 /usr/sbin/cron -f
19067 pts/0    S+     0:00 grep --color=auto cron

I believe the path of cronjob is set as wrong. But how can I rectify this, I can't understand. Any help is appreciated.
