Questions regarding Power of LED´s on Altair 8800 Emulator

-

hello,

first of i´m not native english don´t judge grammar please. second i´m new electronic stuff , want kind of stuff after build.

so, trying build altair 8800 of arduino mega 2560 [https://create.arduino.cc/projecthub/david-hansel/arduino-altair-8800-simulator-3594a6]
i took shematics [https://goo.gl/bqxnx3] , think can of question asking myself how can provide power switches , led´s if there 5 x 5v pins saw picture of inside [https://goo.gl/8kcozh] , asked myself how did ? have ideas don´t seem right. there available? much.
