There are some steps that done for you! You would only do these if at home with a new pi. See them here
Default username is: pi
Default password is: raspberry
If you are on the lick campus, make sure you are connected to StudentNet
Look for a number (written on tape) assigned to your raspberry pi.
Go to this list and find the static IP of the device
On YOUR laptop or other computer, open the terminal(mac) or windows command prompt, and type
ssh pi@”enter_pi_IP_here” and press enter what is ssh?
(for example if I have pi number 11 I type : ssh pi@10.1.8.131)
If that doesn’t work try sudo ssh pi@enter_pi_IP_here (if you use sudo the first password you are asked for is YOUR computer’s login)
When asked for the password, the default password for the raspberry pi is raspberry
Download VNC Viewer to YOUR laptop: https://www.realvnc.com/en/connect/download/viewer/
You can enable VNC Server at the raspberry pi’s command line using raspi-config:
sudo raspi-config
7. Now, enable VNC Server by doing the following:
Navigate to Interfacing Options.
Scroll down and select VNC > Yes.
8. Now open the VNC Viewer app on your laptop and connect to your Pi.
Start by entering the IP address of your pi in the bar at the top of the viewer window:
9. You’ll then get an authentication panel
Remember: the default username is “pi” and the default password is “raspberry”
What if “can’t show the desktop?”
10. You will see the RPi’s Graphical User Interface. The Pi will default to VGA output which is only 640x480 pixels. Let’s change this:
In the raspberry pi’s command line type (after the “$”):
sudo raspi-config
and press enter.
Using the Arrow keys: press enter once you’ve highlighted “Display options”
Navigate to the display settings and set the resolution to something that is at least 700
pixels in both directions.
You will then be prompted to restart.
In the command line type (after the “$”):
sudo shutdown now
and press enter.
When the green light stops flashing, you can unplug the pi. The red light will not shut off.
11. It is also recommended that you change the VNC picture quality to HIGH:
