3. Open Wifi.py.
4. In the WiFi class change the ssid and pswd to the ssid and pswd of the same network the Raspberry Pi uses.
5. Choose a static_address for the FiPy to use within the network. Make sure the static_address is a valid not used ip_address in the network.
6. Save Wifi.py.
7. Upload the code to the FiPy. For Windows using VSCode + Pymakr press F1 and then Pymakr> Upload Project.
