    1 - Introduction

    In this lesson, we will create a project to turn your PICO W into a Wifi Signal Strength Scanner. To begin, connect your Raspberry Pi Pico to either:

    • your computer using a micro USB cable.
    • your iPad using a micro USB cable and a iPhone/iPad to USB adapter.

    2 - Choose Your Editor

    Depending on the device you are using, you will need to use a different editor:

    • If you are using a PC or laptop, open your web browser and go to code.circuitpython.org.
    • If you are using an iPad, download and install the Koder app from the App Store.

    3 - Connect the Editor to Your Pico

    If you are using the CircuitPython editor (code.circuitpython.org) then we need to connect the editor to your PICO W so that we can transfer code to it.

    You can skip this step if you're using an iPad.

    4 - Create a New File

    Create a new file in your chosen editor and with the name 'code.py'.
