NOTE: I have a raspberry pi 3 B+ already configured from CPE 390

Lab 1:

Lab A: NOOBS and Wi-Fi

1. Raspberry Pi only supports SDHC (High Capacity up to 32GB) cards with the FAT (File Allocation Table) file system

2. On a laptop, download the latest New Out-Of-Box Software (NOOBS) zip file and extract the zip file to a folder

• Insert a new or reformatted SD card, go to the folder, select all items, then drag and drop them to the SD card
• Eject the SD card properly, and insert it to Raspberry Pi SD card slot

3. Install NOOBS first at Burchard 123 on the Stevens Wi-Fi network by connecting Raspberry Pi to a monitor, keyboard, and mouse, then to power

• Click "Wifi network (w)," select "Stevens," enter Stevens Username and Password — once connected, more operating systems become available
• Select "Raspbian Full [RECOMMENDED]" and "English (US) Language and Keyboard"
• Click "Install (i)" and OK — installable without the internet access
• Click OK after "OS(es) Installed Successfully" to reboot

4. After reboot, change Password (default: raspberry) and skip both Wi-Fi and update

Lab B: Configuration

1. Click the Raspberry Pi icon at the left of the menu bar to open applications menu > Preferences > Raspberry Pi Configuration > System

• Change Hostname (default: raspberrypi)
• Disable "Auto login"
• Enable "Network at Boot" to "Wait for network"
• Disable overscan if there is a black border on the display

2. Raspberry Pi Configuration > Interfaces

• Enable SSH, VNC, SPI, I2C, Serial Port, 1-Wire, and Remote GPIO
• Disable Serial Console

3. Click OK

4. Click Yes for "Would you like to reboot now?"

Lab C: Startup Mailer - the following steps require the internet access

1. Enable Google 2-Step Verification and generate a Google App password

• My Account > Sign-in & security > Signing in to Google >
• 2-Step Verification > TURN ON > Select a second verification step > Authenticator app (Default)
• App passwords > Select the app (Mail) and device (Raspberry Pi) > GENERATE

2. Click the Terminal icon at the left of the menu bar to open a Terminal and enter

$ git clone https://github.com/kevinwlu/iot.git

$ cp ~/iot/lesson1/startup_mailer.py .

• "~" represents the directory /home/pi
• "." represents the current directory

$ nano startup_mailer.py

• Change RECIPIENT_EMAIL, GMAIL_USERNAME, and GOOGLE_APP_PASSWORD
• Replace HOSTNAME with the new Hostname
• Save the file by typing "control-x y enter"

$ sudo nano /etc/rc.local

• Add the following line with two-space indent above fi at the end as follows

  python3 /home/pi/startup_mailer.py

fi

• Save the file by typing "control-x y enter"

$ sudo reboot

3. Make /lib/systemd/system/rc-local.service executable if it's not

$ ls -l /lib/systemd/system/rc-local.service

$ sudo chmod +x /lib/systemd/system/rc-local.service

4. Check RECIPIENT_EMAIL for Hostname IP address

5. Disconnect the monitor, keyboard, and mouse

Lab D: SSH and VNC

1. On a laptop, download VNC Viewer https://www.realvnc.com/download/viewer

2. Open a Terminal (or PuTTY) and enter

$ ssh pi@155.246.x.x

pi@raspberrypi:~ $ vncserver

3. Open VNC Viewer, and enter 155.246.x.x:1, username pi, and password

4. Click the Web Browser icon to launch Chromium

5. Always shutdown Raspberry Pi properly from the applications menu or from the Terminal

$ sudo shutdown -h now

6. Always unplug the power after the Raspberry Pi green LED blinks ten times

Alternative 1: VNC Connect

• VNC Connect is included with the latest NOOBS for non-commercial use
• Sign up for a free RealVNC https://www.realvnc.com account (need to be over 16) by an email address
• On the Raspberry Pi desktop, click the VNC Server icon at the right of the menu bar and sign in to enable cloud connectivity
• On a laptop, sign in to VNC Viewer

Alternative 2: Serveo Port Forwarder

• On a Raspberry Pi, copy two files

    pi@UNIQUE_NAME:~ $ cp ~/iot/lesson1/startup.cnf .

    pi@UNIQUE_NAME:~ $ cp ~/iot/lesson1/sshscript.sh .

• Edit sshscript.sh with a unique hostname

    pi@UNIQUE_NAME:~ $ sudo nano sshscript.sh

    #!/bin/bash   

    while :   

    do   

    ssh -R UNIQUE_NAME:22:localhost:22 serveo.net   

    sleep 10  

    done

    pi@UNIQUE_NAME:~ $ chmod +x sshscript.sh && sshscript.sh

• Edit /etc/rc.local

    $ sudo nano /etc/rc.local

    ...

    if grep -q "RunServeoSSHOnStartup=1" /home/pi/startup.cnf; then sudo /home/pi/sshscript.sh &  

    fi 

    exit 0

• On a laptop, run the following command

    $ ssh -J serveo.net pi@UNIQUE_NAME
