Input_pullup
This example demonstrates the use of INPUT_PULLUP with pinMode(). It monitors the state of a switch by establishing serial communication . Additionally, the INPUT mode explicitly disables the .
These built-in pullup resistors are accessed by setting the pinMode() as INPUT_PULLUP. This effectively inverts the behavior of the INPUT mode, where HIGH . Bouton poussoir connecté au pin en mode INPUT_PULLUP. Mode INPUT_PULLUP : l'Arduino lira les informations reçues, mais le pin sera .
If you prefer to use these instead of external pull-down resistors, you can use the INPUT_PULLUP argument in pinMode(). In this case, we use the set the pinMode to be 'INPUT_PULLUP' like this:. The pin mode of INPUT_PULLUP means that the pin is to be used . This program shows the use of INPUT_PULLUP with pinMode( ). It monitors the state of a switch by establishing serial communication between your Launchpad.
Chân kỹ thuật số có thể được sử dụng như là INPUT, INPUT_PULLUP , hoặc OUTPUT.
