I have been doing the Arduino Uno Projects for a class and I ran into some trouble with project 15. In the book it wants me to use a sound board which I do not have access to. My professor suggested that I use a cheap pair of earphones instead. I was unsure of how to execute this project because the book does not correlate with what I am trying to do. My idea is to hack a press button that will operate the headphones. I attached a picture of my wiring. If someone could give me feedback on this and point me in the right direction I would greatly appreciate it.
