download and install processing

Since I only have a basic knowledge on programming, I decided to make GUI with processing. Processing is very similar with arduino because arduino originally based on processing.



-Download and install Processing here

Basic command for processing

setup()
-The setup function run once when the program starts like arduino setup().
draw()
-the draw function continuously executes until the program is stopped like arduino loop().
print()
-the print function writes to the console area, the black rectangle at the bottom.
size()
-the window size width and height in units of pixels. the size() function must be the first line of code inside setup.
background()
-set background color of the window.
fill()
-fill the color of the shape.
stroke()
-draw borders of the shape.
rect()
- Draws a rectangle.
ellipse()
- Draws an circle, oval.

First, I tested to arduino. I coded when mouse clicked, led turns on and off and the window color changes black and whitein in order.

Processing Utrasonic Sensor

- I have to change above 2 lines. Erase mySerial.println("cm"); because I only needed distance value for porcessing code. and changed print to println to send '/n' to processing code.
