This is a excellent tutorial for those who are just starting out with the Raspberry Pi 4. The tutorial is presented by the Raspberry Pi Foundation and can be found here.

cd PiClock
cd Clock
cp ApiKeys-example.py ApiKeys.py
sudo nano ApiKeys.py

You need to install a couple of packages:

sudo apt-get install python-qt4

pip install rpi_ws281x

git clone https://github.com/n0bel/PiClock.git

First you need Mapbox key from  here. The Darksky key  from here.  This will tell Pizilla  what you current weather  and forecast should be and set up the radar on your clock. Once you have them to need to be included in the config file.

cd PiClock
cd Clock
cp ApiKeys-example.py ApiKeys.py
nano ApiKeys.py

Now you can edit the ApiKeys.py to include the keys:

dsapi = 'YOUR DARKSKY API KEY'

mbapi = 'YOUR MAPBOX ACCESS TOKEN'

We need to get our  Latitude and Longitude. I found mine in Google Maps.

cd PiClock
cd Clock
cp Config-Example.py Config.py
sudo nano Config.py
