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.

## References and Links

- [Guide to creating ssh keys](https://pimylifeup.com/raspberry-pi-ssh-keys/) Of note, this guide is a little dated as it suggests using RSA keys and many people are moving toward EDCSA keys.

We had trouble getting it to work in 2026 due to some changes in Raspberry Pi OS.

## For the Future

|
- [Setting up Zeroconf to use local names (.local) to access your Pi](https://learn.adafruit.com/bonjour-zeroconf-networking-for-windows-and-linux): this does not work on iot-research because multicast and MDNS are broken.

## TODO

- Finding the Pi using `nmap` or `arp`

|
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"
