WebTo set an output pin high (3.3V) or low (0V), use digitalWrite(pin, value); where pin is the digital pin, and value either 1 or 0 (or HIGH and LOW). To read an input, use digitalRead(pin); To enable PWM on a certain pin, use analogWrite(pin, value); where pin is the digital pin, and value a number between 0 and 1023. WebA pin may also be configured as an INPUT with pinMode(), and subsequently made HIGH with digitalWrite().This will enable the internal 20K pullup resistors, which will pull up the input pin to a HIGH reading unless it is pulled LOW by external circuitry. This can done alternatively by passing INPUT_PULLUP as argument to the pinMode() funtion, as … WebApr 11, 2024 · Defining Pin Levels: HIGH and LOW.

WebSep 18, 2024 · Say that a signal that goes to this pin is a 1 or HIGH. Since Pin 4 is active low, it will end up being a 0 or LOW for this pin. The opposite is true: If the signal leading up to the pin is 0 or LOW, then Pin 4 will be 1 or HIGH. The purpose for a signal to be active low is to have some type of external logic device to turn off the signal.
