Potentiometer: A variable resistor with three terminals that allows you to adjust resistance and divide voltage. It’s commonly used for controlling signals like volume, brightness, or other adjustable parameters.
🔍 Key Functions
Variable Resistance: Adjusts resistance based on the position of its knob or slider.
Voltage Divider: Provides a variable output voltage proportional to the position of the control, useful for fine-tuning signal levels.
🔧 Types of Potentiometers
Linear Potentiometers: The resistance changes evenly across the scale.
Logarithmic (Audio Taper) Potentiometers: The resistance changes in a logarithmic manner, which is ideal for audio applications like volume control.
Rotary and Slider Potentiometers:
Rotary: Most common, where you turn a knob.
Slider: Often used in user interfaces for more direct, linear control.
🎯 Applications
Audio Controls: Used in amplifiers and mixing boards to adjust volume.
Lighting Controls: Adjust brightness of LEDs or display backlights.
Signal Adjustment: Fine-tuning analog circuits for sensors, radios, and other electronics.
User Interfaces: Commonly found on control panels and other devices for intuitive adjustments.
