Pull Up Schaltung Arduino. Check in the serial monitor when you press the button you ll get a logic low and without pressing a logic high with the pull up resistor int buttonpin 3. Well as for any microcontroller e g.

See the digital pins page for details on the functionality of the pins. For any microcontroller in an embedded system such as arduino pull up and pull down resistors utilize input and output signals for communication with external hardware devices the general purpose input output gpio. So to fix this we connect the tact switch pin that is connected to the arduino digital pin to either ground or 5v depending on what we are trying to read when the switch is pressed.
These resistors hold the i o pin at a known value until the switch forces the i o pin to a different known value.
Configures the specified pin to behave either as an input or an output. So to fix this we connect the tact switch pin that is connected to the arduino digital pin to either ground or 5v depending on what we are trying to read when the switch is pressed.
