Installation procedure

Connect the device to our computer using a UBC-C cable; a drive labeled 'RPI-RP2' will appear.

Download the code

Copy the 'adafruit-circuitpython-raspberry_pi_pico-en_US-9.?.uf2' file to the drive and patiently wait for it to reboot!

Once it restarts, you should see a new drive named 'CIRCUITPY'

Transfer the library folder (src/lib), followed by the src/boot.py file. Adjust the settings in the src/config.py (modify call/settings) and transfer it to the 'CIRCUITPY' drive.

Finally, transfer the src/code.py file!
