Materials:
After revisions to my project due to feedback from my Instructor and Ta, I have decided to make an instrument spanning two octaves starting on c4 and ending on b5. The sound circuit will be very simple, going from digital output pin 2 of the arduino through a 100 ohm resistor, and one capacitor into the positive terminal of the speaker, and the other speaker terminal going to ground. I am going to make a 5x7 led matrix that will utilize a 5x5 portion for the project. The LED's and the sound circuit will be mounted on an unprinted circuit board. This circuit board has 19 one inch or so pieces of stiff wire soldered into it to act as pins, so the whole circuit board simply plugs directly into the top of the freeduino. There are 5 analog inputs, 11 digital outputs, 1 +5v, 2 Gnd. The control of the device is an analog joystick with x and y axis, 2 buttons, and an adjustment wheel that I am using as a third button. There will be three different modes of interaction: In Free play mode the user only has to move the joystick around on the x and y axis to produce the respective tones. In selective mode the user will move the stick to any position, but the sound will only be produced when the user presses the trigger button. For demo mode, the user simply pushes the top button and a preprogramed melody will play.
Melody Demo:
Uppercase letters are sharp, lowercase are normal notes.
