Hooking up a seven segment LED display

I thought it'd be fun to hook up an old fashioned 7 segment LED display using the driver IC that came in the TTL chip kit! [This is my first attempt at a 4K video (still using an iPhone and a Yeti, but this time I captured with https://reincubate.com/camo/ instead of OBS). I also tried to improve(?) the audio levels in this one, but i find that whole a process a bit of a dark art so I don't know if it worked out or not.] -- Links 7 Segment Display Data Sheet: http://www.xlitx.com/datasheet/5161AS.pdf SN74LS48N Data Sheet: http://hlf-ic.cn/upload/202108/SN74LS48N%20HLF.pdf 7 Segment Display: https://amzn.to/3viAu1l TTL ICs: https://amzn.to/40WH75c Breadboard kit: https://amzn.to/3MYwfho Power supply: https://amzn.to/3uAYxIE Antistatic mat: https://amzn.to/49RhcQi My Wife's Books: https://amzn.to/47yt9Ji (Maybe you and/or someone you know will like them!)
