Seven segment display (ssd) is a display device usually used to show decimal number system. Popular physical form of seven segmen display is:
there are types of 7 segmen:
Can be seen 7 segments have 10 pin:
each is combination of segments (usually use led) is arranged like picture above. Base form of 7 segment as follows:

 |  can be seen, there are 7 segmen (segment a,b,c,d,e,f, and g) and a point is denoted with P (abbreviation of "point") |  |

Can be seen 7 segments have 10 pin:
- For 7 segment typed cathode, there are pin a,b,c,d,e,f,g,dp,gnd,gnd
- For 7 segment typed anode, there are pin a,b,c,d,e,f,g,dp,vcc,vcc

Common Katoda | Commond Anoda |
Use 7 segmen display:
- Example on 7 segment typed cathode, we want to turn on segment a by using DC supply, connect positive of supply to pin 7 of seven segment display with 150 Ω resistor, and connect negative of supply to Gnd/ground (pin 3 or pin 8 of seven segment
- Example on 7 segment typed anode, we want to turn on segment a by using DC supply, connect positive of supply to Vcc (pin 3 or pin 8 of seven segment) with 150 Ω resistor, and connect negative of supply to pin 7 of seven segment
