The pin state

Webb21 maj 2024 · Pin.value ( [x]) This method allows to set and get the value of the pin, depending on whether the argument x is supplied or not. If the argument is omitted then this method gets the digital logic level of the pin, returning 0 or 1 corresponding to low and high voltage signals respectively. Webb9 mars 2024 · NOTE: Digital pin 13 is harder to use as a digital input than the other digital pins because it has an LED and resistor attached to it that's soldered to the board on most boards. If you enable its internal 20k pull-up resistor, it will hang at around 1.7V instead of the expected 5V because the onboard LED and series resistor pull the voltage level …
