## Background
One of the reason I discoverd curiocity towards electronics was when my grandfather showed me his oscilloscope when I was 10 or so. Thats why I got inspiration to plan and design this art. I want people without knowledge about elecctronics to be able to understand what struck me when I was 10, and share the excitement I had blindly adjusting the wave on oscilloscope display.

## Items
- Linkit 7697...Controls whole device.
- 8*8 LED display...To show wave.
- Analog joystick...To adjust vertical position of wave.
- Potentiometer...To adjust pitch of wave.

## Function
```flow
st=>start: Start
e=>end: End;

op1=>operation: Display default wave
op2=>operation: Display updated wave
op3=>operation: Shift wave vertically
op4=>operation: Shift wave horizontally
op5=>operation: Change wave pitch

cond1=>condition: Joystick vertical change ?
cond2=>condition: Joystick horizontal change ?
cond3=>condition: Potentiometer change ?

st->op1->cond1
cond1(yes)->op3->op2
cond1(no)->cond2
cond2(yes)->op4->op2
cond2(no)->cond3
cond3(yes)->op5->op2
cond3(no)->op2
op2->cond1
```
