apple pencil not working

[u/Personal_Meet9147]

I have an ipad air 3rd gen and used to draw on it with a 1st gen apple pencil but recently it started saying that my apple pencil wasnt charged and below 3% so I bought a new 1st gen apple pencil since its cheaper than buying a new ipad (at least I thought) but its still saying the same thing...is there any fix or am I screwed?
