7 Segment Display Common Anode (Pack of 5)

7 Segment Display Common Anode

Overview

The 7 Segment Display Common Anode is a type of LED display used for displaying decimal numerals and some alphabetic characters. It features seven individual segments arranged in a figure-eight pattern, with an additional segment for a decimal point. This display is known for its simplicity and effectiveness in numeric displays.

Features

• Configuration: Common Anode, where all the anode terminals of the LEDs are connected together. The display lights up when a LOW signal is applied to the respective segment cathodes.
• Segments: 7 segments arranged in a figure-eight configuration, plus an optional decimal point.
• Display Type: LED, providing bright and clear numeric display.
• Current Rating: Typically operates at around 20mA per segment, suitable for general-purpose displays.
• Color Options: Available in various colors such as red, green, blue, and yellow.

Applications

• Digital Clocks: Used to display time in digital clock projects.
• Counters: Ideal for displaying numerical counts in counters and meters.
• Electronic Meters: Displays readings in voltmeters, ammeters, and other measuring instruments.
• DIY Projects: Commonly used in hobbyist projects for numeric display purposes.

Working Principle

In a common anode 7-segment display, all the anodes (positive terminals) of the LEDs are connected to a common power source. To light up a segment, a LOW signal is applied to the corresponding cathode (negative terminal). This setup requires a current-limiting resistor to protect the LEDs and ensure proper operation.

Advantages

• Simplicity: Easy to interface with microcontrollers and digital circuits using simple logic signals.
• Brightness: Provides bright and clear numeric displays with good visibility.
• Versatility: Suitable for a wide range of applications, from clocks to counters.

The 7 Segment Display Common Anode is an effective and versatile component for various electronic projects, offering a straightforward solution for displaying numeric information.
