WebPin objects are callable. The call method provides a (fast) shortcut to set and get the value of the pin. It is equivalent to Pin.value([x]). See Pin.value() for more details. Pin.on ¶ Set pin to “1” output level. Pin.off ¶ Set pin to “0” output level. Pin.mode ([mode]) ¶ … WebFeb 10, 2024 · Connect a tactile switch with one side connected to pin 1 of the expander. Add a ~10K pull-up resistor on the expander pin 1 to Vin. Connect the other side of the button to ground. This makes it so the button pin is HIGH by default, and when you press the button, the pin goes LOW. LED+ to breakout GPIO 0 LED- to 1K resistor
