Scripts and documentation for setting up a Raspberry Pi (Zero W 1 or 2) for use in Mechatronics 1 or Cyberphysical Systems.  This single-board Linux computer is equivalent in power to the Raspberry Pi 2 but in a smaller form factor, includes WiFi and Bluetooth, and is very affordable at 15USD.  For operations that need higher computing power, we recommend the Raspberry Pi 3 or 4 which can be purchased later.

1.    Check for list of networks:  nmcli device wifi list
1.    Show details of "preconfigured" network:  nmcli connection show preconfigured
1.    Change the SSID (which wireless network you will connect to) in the "New_SSID": nmcli connection modify preconfigured wifi.ssid "New_SSID"
1.    Change the wireless access password in the "New_Password":  nmcli connection modify preconfigured wifi-sec.psk "New_Password"
