1.10 7-segment Display
A 7-segment display is an 8-shaped component which packages 7 LEDs. Each LED is called a segment - when ener-
gized, one segment forms part of a numeral to be displayed.
There are two types of pin connection: Common Cathode (CC) and Common Anode (CA). As the name suggests, a CC
display has all the cathodes of the 7 LEDs connected when a CA display has all the anodes of the 7 segments connected.
In this kit, we use the Common Cathode 7-segment display, here is the electronic symbol.
