Robomart Single Digit Common Anode Seven Segment Display

Single Digit Common Anode Seven Segment Display is a light weight easy to use break out module. This Single Digit Common Anode Display is compatible with any circuit and any microcontroller module. The 7-segment display, also written as ?seven segment display?, consists of seven LEDs (hence its name) arranged in a rectangular fashion as shown. Each of the seven LEDs is called a segment because when illuminated the segment forms part of a numerical digit (both Decimal and Hex) to be displayed. An additional 8th LED is sometimes used within the same package thus allowing the indication of a decimal point, (DP) when two or more 7-segment displays are connected together to display numbers greater than ten. Each one of the seven LEDs in the display is given a positional segment with one of its connection pins being brought straight out of the rectangular plastic package. These individually LED pins are labeled from a through to g representing each individual LED. The other LED pins are connected together and wired to form a common pin. So by forward biasing the appropriate pins of the LED segments in a particular order, some segments will be light and others will be dark allowing the desired character pattern of the number to be generated on the display. This then allows us to display each of the ten decimal digits 0 through to9 on the same 7-segment display. The displays common pin is generally used to identify which type of 7-segment display it is. As each LED has two connecting pins, one called the ?Anode? and the other called the ?Cathode?, there are therefore two types of LED 7-segment display called: Common Cathode (CC) and Common Anode (CA).
