Above is the wiring visible.
Step 3: Coding
Here's the code. Check your wiring and the pins used in the code.
Step 4: The Case: Box
The case is fairly simple. The box contains the LEDs, the buzzer and the arduino. I used a PCB for the the LEDs and the buzzer. In my case I used an old phone case.
Step 5: The Case: Base
The base contains the servo and potentiometer.
Step 6: Elektronica, Assemble!
I used a cable to power the arduino. Make a small hole in the back for wires from the potentiometer and the servo.
