Newby looking to choose the correct Arduino and accessory components

  • There are different NANO form factors out there.
    Confirm you are using the proper silk screen pin labels on your particular PCB.

You need a relay, as others have said before the conversation derailed.
AFAIK, there aren't any "convenient" Arduino-compatible boards with any built-in relays (relays are big, and it would tend to make the board "large.")

Nor do I see mini "relay shields" for an Arduino Nano (which is otherwise a fine choice for this application.) (which is ... a bit strange. Although a lot of relay add-ons for Arduinos seem to aim at higher-current applications, whereas you just need a switch closure.) It would be easy enough to wire up the circuit from #4 with a small 5V relay, or you could use an Adafruit feather with their relay featherwing if you want a nice neat package.

(You could also presumably wire the featherwing to an ordinary nano; only slightly more difficult.)

(General "newby" advise is to get an ATmega328p Arduino Uno R3 or compatible. Almost all of the examples and tutorials created over the last 15+ years are likely to be done with that hardware. A 328p-based Nano is a good second choice (same CPU and software, different physical layout.) Avoid the "Uno R4" boards (a bit sadly.))

The first step to making Canada the 51st state, and it happened 17 years ago.

A BILL FROM THE US CONGESS VIA CHAT GPT

To designate Canada Dry Ginger Ale as the official state beverage of the 51st State of the United States.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

This Act may be cited as the “51st State Official Beverage Act of 2025.”

SEC. 2. FINDINGS.

Congress finds the following:

  1. The 51st State, officially admitted to the Union on [Date of Admission], has a rich and diverse culture that merits its own state symbols.
  2. Canada Dry Ginger Ale has enjoyed widespread popularity and cultural significance in the region comprising the new state.
  3. The beverage is recognized for its crisp taste, longstanding heritage, and association with American households and celebrations.
  4. Designating an official state beverage reflects the customs, tastes, and identity of the state's residents.

SEC. 3. OFFICIAL STATE BEVERAGE.

Canada Dry Ginger Ale is hereby designated as the official state beverage of the 51st State of the United States of America.

SEC. 4. EFFECTIVE DATE.

This Act shall take effect on the date of its enactment.

Yes, we want to use a motion sensor to initiate the relay closure. I have the correct PIR motion sensor and 5 volt relay module. I selected a Nano RP2040 with the appropriate screw terminal board for the project. Currently I am having trouble with the coding, as we wanted to have a minimum 30 second delay between opportunities for the relay to close. At any rate, I guess I’ll put together a new post since I am pulling my hair out trying to make this work.
