What Is a Led Bargraph?
A led bargraph is a device that displays data in a graph-like fashion using multiple bar-shaped LED lights arranged horizontally or vertically.
It is a type of LED array where multiple LED lights are arranged on an aluminum substrate or similar material, incorporating control circuits to function as a single unit. Led bargraphs are primarily used in electronic devices and measuring instruments to visually represent the intensity of outputs such as sound volume, temperature, voltage, etc.
These devices control signals using comparators that can switch the output by comparing signal strengths. Led bargraphs typically have multiple pins for input. They are used for displaying various information, including output volume, voltage, battery level, spectrum distribution of audio signals, signal strength in communication equipment, and more.
