WebPull-up and pull-down resistors are not a special type of resistor but simply a constant value connected via, mainly, + 5V and pin or GND and pins. Resistor between pin and + 5V is called pull-up resistor, while the one between the pin and GND is a pull-down resistor. The default value of this resistor is 4.7kΩ or 10K, but more about that later.
