Sketch 1

Based on the Sparkfun tutorial I have tested the connection between Processing and Arduino

When I press the mouse button inside the processing box ,the led on my board will turn on and when I press again it will turn off

Sketch 2

Now I will test a simple serial connection with the ldr value of my previous Board B1

Code explanation:
In Arduino code the ldr value is checked , if the value is higher than 500 than it will send 1 on the serial if not it will send 0
In Processing software the code reads the value received on the serial and if it is equal to 0 than it will draw a rectangle with black color "fill (0)" if else it will change the color to grey "fill (204)"

After that I have made some adjustments in the code and changed the size of the display from 200x200 to 400x400 and change the rectangle to circle.

After that I have changed the background color and added a text showing the received values

Sketch 3

Now I will test another simple serial connection with a Potentiometer connected to my Board B1

Sketch 4

Now I will control the Led on Pin13 with the Potentiometer connected to my Board B1

The background color will change with the potentiometer value and the led is controlled by the mouse buttons: left click will turn on the led and the right-click will turn off the led.
