How Character LCDs work - Part 1 (Patreon)

This will be a two parter (unless everyone hates the first part)

I'm a little late getting a new video out.  I've started 3 videos this month that all had to be shelved temporarily due to problems such as shipping delays and broken/uncooperative hardware.  So, I jumped to this video ahead of schedule.   Let me know if you think this video is too technical, or doesn't go deep enough, or is just right.
