HELP ASAP. Need someone to build circuit connected to 7 segment display.

[ErickVioland]

Im new here and have to build a circuit that connects to 7 segment display when two numbers are entered.

I already made the functions and all but I cant understand how to connect the lines to the display so it turns on. I dont know when to put the source and how much voltage it needs or when I need to put resistors. 

Can someone build the circuit for me to show me how its done and what it needs. Its urgent for tomorrow help please.

Hello Erick,

I feel like it will be better to search on the internet for a tutorial or an example of a circuit with a 7 segment display. 

Here I found one tutorial https://www.electronics-tutorials.ws/blog/7-segment-display-tutorial.html

I hope this helps!
