I am trying to understand the basics of electronics and I often come across the terms pull-up and pull-down resistors. From what I understand these resistors help the switching logic devices like transistors.
Could you help understand the basics of these components in simple terms.
I am trying to build a small feed back system that uses a transistor as switch. The system uses a buzzer that makes a sound when the yellow and gray components meet. The problem that I am facing is that the buzzer keeps making a low volume sound even when the components are not touching. I was reading about pull up and pull down resistors and would like to know how to implement it here
