The Pull-Up Resistor: How It Works and Choosing a Value

Webb9 mars 2024 · Most resistors can handle only up to 0.25W. Rule of thumb. The rule of thumb when choosing a pull-up resistor is to choose a resistance value that is at least 10 times smaller than the input impedance (or the internal resistance) of the pin. Often, a pull-up value of 10 kΩ will do the trick. But if you want to understand how it works, keep ... Webb23 apr. 2013 · Location Pancevo-Belgrade, Serbia Activity points 37,363 ...
