Works As Expected
I really like how well-made and sturdy this LED display is. The segments light up brightly.
7 Segment Led Display (Common Anode), is a form of an electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
The Common Anode (CA) - In the common anode display, all of the LED segment anode connections are connected to logic "1." Individual segments are illuminated by applying a ground, logic "0" or "LOW" signal to the Cathode of the specific segment via a suitable current limiting resistor (a-g). Common anode displays are more popular in general because many logic circuits can sink more current than they can source. Also, a common cathode display is not a direct replacement in a circuit for a common anode display, and vice versa, because it is equivalent to connecting the LEDs in reverse, and thus no light emission occurs. The specific set of LEDs is forward biased depending on the decimal digit to be displayed.
Seven-segment displays or ( 7 segment displays) are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information. If you want to use 7 Segment Led Display in your Arduino project, then you will need a few components like breadboard , jumper wires , resistors , capacitors and transistors.
