V3 Pico IO with momentary button

I was able to use a momentary switch on my PixelBlaze v2 by connecting it to GP04 and ground, then use “pinMode(4, INPUT_PULLUP)” in the pattern code. Can I do something comparable with the PICO?


You can do something similar with gp0, which is on a small pad on the underside. It’s the one labeled 0, the bottom right of the 6 pads. This pin is used to put the MCU in bootloader mode though, so you want to make sure it isn’t pulled low during startup/reset.
