I'm working on a project which involves a mini talkbox.I want to send a square wave using the tone library
and does the resistance matter if the speaker connects straight to ground?
Sorry I thought the resistance value might've only applied after current ran through the speaker.
So I'd still be good to go if I use the 5V pin for power. Assuming the current from the pin is 400 mA I'd get around 0.25W
What I'm trying to do is fit the speaker into a small container which leads to some flexible polytube which goes in the mouth of the user to talk over the square wave, kinda like what you here on Daft Punk songs (this kinda shows the same idea: https://youtu.be/NxF6FQA0hQs) Would that be loud enough to make noise when the audio exits the person's mouth, similar to the video?
