◆ BTN0_PIN

#define BTN0_PIN   GPIO0

Default button GPIO pin definition.

Wemos S2 mini boards have a BOOT button connected to GPIO0, which can be used as button during normal operation. Since the GPIO0 pin is pulled up, the button signal is inverted, i.e., pressing the button will give a low signal.
