I need 12V of AC power. What’s the best way to get there. I’m in North America so I’m on 110V.

You don't mention the current it has to deliver?
Although most plug into a mains socket adapters convert the mains voltage to some regulated dc value to charge a battery I have bought ones that output an ac voltage without converting it to dc voltage. An electronics outlet might have something to suit.
A basic conversion is a simple transformer that can handle the current required. It is safer to have the transformer in a plastic plug in a mains module that cannot be opened so there is no contact with the mains voltage by the user.

@mtlatc I just did a google and found these https://amz.run/6m1R https://amz.run/6m1S lot's more.
Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define

Most wired garden lights were 12AC (That was before the solar lights became popular). I think you can still purchase those transformers in the big box stores.

@robotbuilder I only need .8A
@zander I was hoping for something a bit cheaper. It only cost me about $4 to build the circuit. I did see some others on Jameco but they were still in in $15 range.
@rcc1 I’ll take a look, thanks.

@mtlatc I hear you, but the problem is because it's AC it will likely involve a transformer and that means some amount of copper wire. As you may know, criminals are ripping the copper wire out of unoccupied houses etc due to the high cost of copper now. What I would do is find a part you favour then source it on AliExpress. That will often be much less expensive.

@mtlatc, Try looking at this link: "https://www.amazon.com/AGPTEK-Converter-Transformer-Waterproof-Spotlights/dp/B00WUARESY/ref=sr_1_27?crid=3UT8ILDNEQ80V&keywords=120vac+to+12vac+transformer&qid=1686533297&sprefix=120Vac+to+12Vac%2Caps%2C750&sr=8-27"
it for a 120 vac to 12 vac 2.1A ( 24 watts) for around $30 US. This is probably or this one that is just a power transformer 120VAC to 12VAC , 10VA, 1000mA, or about 12 watts fo about $16 US link: "https://www.amazon.com/XZGm-Transformer-Motor%EF%BC%8CAddress-Light%EF%BC%8CFountain%EF%BC%8CFurnace%EF%BC%8CDewalt-Radio%EF%BC%8CSpeaker/dp/B0B9S1PYWT/ref=sr_1_32?crid=3UT8ILDNEQ80V&keywords=120vac+to+12vac+transformer&qid=1686533297&sprefix=120Vac+to+12Vac%2Caps%2C750&sr=8-32"
