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.

Some Tricks
Here is a page of tricks we have discovered that may involve advanced techniques. Credit: Daníel Bjartur Guðmundsson, transcribed by Joseph T. Foley
- Check for list of networks: nmcli device wifi list
- Show details of "preconfigured" network: nmcli connection show preconfigured
- Change the SSID (which wireless network you will connect to) in the "New_SSID": nmcli connection modify preconfigured wifi.ssid "New_SSID"
- Change the wireless access password in the "New_Password": nmcli connection modify preconfigured wifi-sec.psk "New_Password"
