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.

# Procedure

1. [Raspberry Pi Imager procedure to setup ssh and Raspberry Pi Connect](imager.md)

1. Find out your Pi's ethernet addresss in case you need to find it on `iot-research` again. Type `ip addr show dev wlan0` and for something like `link/ether 01:23:45:67:89:ab`. Write this information (the 12 characters and colons) in your notebook. In T-411-MECH we want you to put this information in a spreadsheet links from the main page: this allows us connect Pi's to people in case of any issues.

|
|
- [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.
