<p>What value pullup resistor should I use for a pushbutton connected to a microcontroller input? ![Image alt text](https://electrical.codidact.com/uploads/VETExY638GNHNBKNKHrLGnEm) <p>I've seen values from 1 kΩ to over 100 kΩ. Some references just say to use 10 kΩ because it's a "good value". How do I calculate this to decide for myself?
