I had to make this for school
Second Step (Aux Jack)
This is the aux jack. I used this for demonstration purposes, as this is a noise machine.
Third Step (On/Off Switch)
This was my last step. I didn't realize that adding a simple switch to the A2 pin would turn off my project. I added it last to make the project more complex

// - A5 = light sensor
// - A7 = pin #6 on board
// - A9 = pin #9 on board
// - A10 = pin #10 on board
// - A11 = pin #12 on board
