7 Segment Display (1x1) Common Cathode 1.2 Inch

The 7 Segment Display is a versatile and widely used electronic component designed to display decimal numbers and some characters. This particular model features a common cathode configuration with a size of 1.2 inches, making it perfect for applications that require visibility from a distance.

Key Features

• Common Cathode Configuration: The common cathode means that all the cathodes of the LEDs are connected together, which simplifies circuit connections, especially in larger displays where multiple segments are used.
• 1.2 Inch Size: This size provides optimal visibility for various applications, ensuring that the display can be read from a reasonable distance.
• Vivid Brightness: The display is designed to emit bright light, ensuring clear visibility even under bright ambient lighting conditions.
• Robust Life Expectancy: With an operational life typically exceeding 50,000 hours, this display is highly durable for long-term applications.
• Easy Integration: The display's pin configuration is made for easy integration into various PCB designs, making it suitable for both amateur and professional electronics projects.

Applications

The 7 segment display is suitable for a wide array of applications, including but not limited to:

• Digital clocks and timers
• Electronic meters
• Scoreboards for games
• Home appliances user interfaces
• Industrial instrumentation
• Arduino and microcontroller projects

Energy Efficiency

This display is designed with energy efficiency in mind, typically operating within a voltage range of 2V to 3.2V per segment. When used in conjunction with appropriate resistors, it can operate at low current (often around 20mA per segment) without compromising on brightness. This makes it an ideal choice for battery-operated devices where power conservation is essential.

How to Use

Using the 7 Segment Display is straightforward. Here is a basic guide on how to integrate it into your project:

1. Connection: Connect the common cathode pin to ground. Each segment pin (labeled a to g, plus the decimal point if available) should be connected to the appropriate output pin of your microcontroller with a current-limiting resistor.
2. Programming: Write a simple program to control which segments light up based on the numbers or characters you wish to display. For example, to display the digit '5', you would light up segments a, c, d, e, and g.
3. Testing: After hooking up, power up your circuit and test your connections by displaying various numbers.
