* Software
** Dependencies
Install packages using these commands:
: $ sudo apt install python-smbus  # Needed for bmp388.py
** BMP388 Pressure sensor
The following command will download a repository containing a python
script that can pull pressure data from the BerryGPS-IMU v3.5's BMP388
: git clone https://github.com/getelectronics/PIBits.git
*** 2020-04-10 Note regarding getting data from BMP388 (task:8a5607fe)

- I ordered another two Raspberry Pi Zero W's and another BerryIMU-GPS.

- I think I found the problem with the pressure sensor. According to a
  2020-03-12 post by johnmark at
  https://ozzmaker.com/forums/topic/temp-barometer/ , the BerryIMU-GPS
  version 3.5 uses BMP388, not BMP280. johnmark posted a link to a
  python script that works for the BMP388 pressure sensor at:
  
    https://github.com/getelectronics/PIBits/blob/master/python/bmp388.py

- I have downloaded this PIBits git repository to jalrasaroa-02 and am
  testing it now. It works.

- I am checking to see how I can automatically update the clock on
  jalrasaora-02 via a network time server. Reading instructions at
  https://www.garron.me/en/go2linux/how-to-set-date-and-time-linux.html
  .

- I am installing the `ntp` package described here:

    https://www.digitalocean.com/community/tutorials/how-to-set-up-time-synchronization-on-debian-10

    $ sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install ntp

  - I confirmed that the ntp time synchronization service is running with:

    sudo systemctl status ntp

- I am creating a git repository to store executables and setup
  instructions for Raspberry Pi Zero W's used for logging:

  - Location (GPS WGS84)
  - Air pressure (Pa)
  - Temperature (°C)
  - Direction (magnetic north heading)
