1. Connect the joystick module and button to your Raspberry Pi Pico:

   • Connect the GND pin on the joystick module to a GND pin on the Pico.
   • Connect the VCC pin on the joystick module to a 3V3(OUT) pin on the Pico.
   • Connect the VRx pin on the joystick module to an analog input pin GP26 on the Pico.
   • Connect the VRy pin on the joystick module to another analog input pin GP27 on the Pico.
   • Connect the SW pin on the joystick module to pin GP16 on the pico.

2. Install CircuitPython on your Raspberry Pi Pico:

   • Download the latest version of CircuitPython for the Raspberry Pi Pico from the CircuitPython website.
   • Connect your Raspberry Pi Pico to your computer using a micro USB cable while holding down the BOOTSEL button on the Pico. This will put the Pico in bootloader mode and it should appear as a USB drive named RPI-RP2.
   • Drag and drop the CircuitPython .uf2 file that you downloaded earlier onto the RPI-RP2 drive. The Pico will automatically restart and install CircuitPython.
   • After installing CircuitPython, the Pico will appear as a USB drive named CIRCUITPY.

3. Install the adafruit_hid library on your Raspberry Pi Pico:

   • Download the latest version of the Adafruit CircuitPython Library Bundle from the CircuitPython website.
   • Unzip the downloaded file and open the resulting folder.
   • Locate the adafruit_hid folder inside the lib folder.
   • Open the CIRCUITPY drive for your Raspberry Pi Pico and locate or create a folder named lib.
   • Copy the entire adafruit_hid folder from the unzipped Library Bundle into the lib folder on your Raspberry Pi Pico.

4. Save the code to the pico with the same name

5. After saving this code to your Raspberry Pi Pico, it will automatically restart and run it.

Once you have completed these steps, you should be able to control the mouse on your PC using the joystick module connected to your Raspberry Pi Pico and use its button as a left mouse button
