Bar Graph LED Display DIP 10SEG red
Bar graph LED displays are commonly used to indicate the level of something, like the sound volume of a sound system. Because each LED on the display has its own set of pins to operate with, it can easily be uses with a microprocessor to process the input data into data that can be used to indicate the level on the bar graph LED display.
Please note that you have to use current limiting resistors when you connect the display to the microprocessor directly.
|Min input voltage||1.5V
|Max input voltage||2.2V|
|Number of pins||20|
