VIVIVIVIVIVIVIVIVIVIVIVIVIVIVIVIVIVIV

Connect via breadboard(or just solder)
Rasberry pi pico GP6---->Arduino button(any pin) Rasberry pi pico GND---->Arduino button(any pin)

Connect to the pc(Rasberry pi pico---->Wire---->pc)
Drop the uf2 file of circuitpython to your pico, it should reboot
Open "lib" folder in explorer
Drag adafruit_hid and adafruit_ticks.mpy from libraries bundle

Open code.py in rasberry pi pico and paste this:

import board
import digitalio
import time

button = digitalio.DigitalInOut(board.GP6)
button.direction = digitalio.Direction.INPUT
button.pull = digitalio.Pull.UP

last = None

while True:
    current = not button.value
    if current != last:
        if current:
            print("down")
        else:
            print("up")
        last = current
    time.sleep(0.01)

Dont run it yourself, and dont use repl(if you dont know what repl is, its even better, also it will run by itself)

Open this folder
Edit buttonbridge.py and include your port with the url of the tunnel
Run playit.gg, wait for it to load
Click the path
Enter cmd
It should open a command prompt
Enter bridge.js in it
Repeat
Enter buttonbridge.py
