IC Series - Episode 00 - Introduction

I bought a bag of integrated circuits (IC) from eBay -- it is about 1/2 a pounds and contains all kids of TTL, CMOS, Semiconductors, etc. And the "etc" is very interesting.

I'm going to go through as many of them as I can and put them on a breadboard, review the datasheet, build up a test circuit, write some Arduino code, and see what I can make them do.

Some of these I will also hook up to my oscilloscope and give them a few tests.

I'm doing this because I love to learn new things and find old ICs fascinating. While these ICs may not be practical anymore with our microcontrollers, it is still a lot of fun to learn how they work, what they were used for, and what we might be able to use them for in the future.

Follow along and learn something about old ICs. ... https://www.youtube.com/watch?v=vo9XHMJ0TMA
