Pull-up-resistor

This video explains how to use pull-up resistors to stabilize a push button connected to a microcontroller. The video demonstrates how electromagnetic interference (EMI) can cause a floating pin to fluctuate randomly, and how a pull-up resistor can fix this problem by pulling the pin high when the button is not pressed. The video also shows how to use built-in pull-up resistors on microcontrollers like the LaunchPad and Arduino.
