I soldered my button touch wire to pin A3, which is also known as GPIO 15 (see the QT Py Pico pinout diagram, it's the number in yellow).
In the LED Settings screen, scroll to the button setup section and set button 1 to use pin 15, with the type set as "Pushbutton".
I advise against using button 0. WLED's buttons have some default behaviors written in, and one of button 0's default behaviors is that when it's pressed for more than a few seconds, it resets your microcontroller to factory settings. I originally had button 0 selected, and I held the button down a bit too long while I was sewing it onto the hat, and .. POOF. All my settings and presets were wiped out.
Check out the "Backup" section under the Additonal Settings page to learn to back up your configuration and presets, in case this kind of thing happens to you.
Next, head to the Time & Macros config screen. Scroll down to the Button actions area.
For button 1, enter the number assigned to the two control presets you made on the last page. My Next_FX preset is number 22, so I entered 22 under "short press", and my Toggle preset is number 21, so I've got that set up as a "long press".
I also added my playlist toggle to preset 20, so a double-click of my button will turn sound reactive mode on or off.
Troubleshooting
If your button isn't working, here are some things to try:
- Double check both the LED preferences page and the Time & Macros page to be sure your settings are correct, and have saved.
- Be sure your presets are correctly numbered. WLED gets confused if the presets have non-sequential IDs (so make sure they're numbered 1, 2, 3 rather than 2, 5, 7).
- Try soldering to a different GPIO pin, and make sure to update the pin number in LED Preferences. I originally soldered to A1, but there was a short or some interference from A0 so giving a little space between the soldered wires on the board seemed to help.
