7 segment digital display

[Digital_illiterate]

I am a senior in highschool. I an assignment to design a circuit on a breadboard using a 74LS47 chip,7 segment digital display, 4 switches and any necessary resistors. The problem is that I (1) don't the function of the chip, (2) I don't know the pins on the chip and (3) have no clue as to where the wires are suppose to go to display 1-10-86 (dashes included). Please Help

The best thing to do is go to google and put in 74LS47. Take a look at the web pages and PDF files.

They will help get you started.

Let us know how thing go

here the datasheet, it gives all the info you need abou the pins
https://www.electro-tech-online.com/custompdfs/2004/03/74ls47.pdf

abcd are your 4 switches, i'm not sure what you wan to display
on a 7 seg, with a chip like that yoou can't display -
do you wan tto display them all at the same time or what, caus eif you do you'll need a display for each digit

how the chip works is it reads in the data to display in binary
eg switch ab off and cd off =0011 in binary which is 3

there a 7 bits to the display labelled a-g,
to disply 3 it needs to switch on bit a,b,c,d,g
see page 3 of the datasheet
