A locker box with audio output.
Finally, we decided to make a locker box with toggle on it to give an input. When the toggles are turning, it will release tones as each tone actually refer to a number(to help understand as a locker box) which consists a password. After each toggles are decided, a check button is ready to be press. If the tones are not exactly the same, a failure music would be played. When each toggles are tuened to an angle of same tone, the correct indication would be activated. and the box will open.
(1) The original code examples of a number locker: for the first step, we made this functioned. It has three toggles, each of which controls 6 numbers. we set a correct number as "5","2","3". When the angle of the tree potentiometers are turned to the right number, the surveillance will out put "Correct!".
(2) Then we tried to combine this to audio output, to make every number represents a tone.
