So I've never worked with an arduino before and was looking for some general advice on a project I wanted to implement! Essentially, I want to have an arduino that will always be connected to LED lights and a speaker. Whenever I send a POST call to a specific web URL or a webhook to this URL, I want the arduino to receive that signal and in turn, flash lights and play a sound. What sort of equipment would I need and how would I go about setting up this project.
Any and all help would be very much appreciated! :)
