@ kingrosekhan123
there can be many ways
there are two types of segments

1) Common Anode (CA)
2) Common Cathode (CC)

it can be interface using decoder ic like CD4011, 74LS47,74LS48, CA3161
It can be directly interfaced with pins of controller if segment is small
CA will more bright as compare to CC
Controller pins can sink current so CA will be bright as compare to CC

see the link below
