This project uses a Raspberry Pi to show the current weather downloaded from OpenWeatherMap on an 16x2 LCD
The corresponding Fritzing file can be found in the images folder.
To check if the display was connected correctly the simple_lcd.py script can be used.
It contains just the minimal configuration to show a message on the display.
The initial configuration of this project can be made by running the setup.sh script file with
source setup.sh
It installs the virtualenv package, if its missing, creates a virtual environment
and install the dependencies listed in requirements.txt.
A systemd unit file is copied to /etc/systemd/system/pi-lcd-weather.service,
which points to the current project location, it then gets enabled to start on boot
and is then started.
The config.ini file contains the OpenWeatherMap API key, a city ID
and the temperature measure unit. The API key can be obtained
here. The city ID can be extracted from the url
after searching and selecting a city here.
Possible values for temperature measure units are metric (for Celsius) and
imperial (for Fahrenheit)
The config.ini file is created if its missing.
If the setup was done with setup.sh, the program can be started with
sudo systemctl start pi-lcd-weather.service
or restarted after a change with
sudo systemctl restart pi-lcd-weather.service
It can also be started by activating the virtual environment first and then executed with
source venv/bin/activate
python lcd.py
Errors are logged into lcd.log
