I'm learning processing software. And so far I've run all the example programs successfully except the "embedded links" and "loading images".  On executionm, the program should open a web browser and connect to a webpage on clicking a button. But, it is not opening a web browser itself . Maybe i have check something before i run this program. I want to learn this example program, I hope it helps me in my upcoming project.

I'm a beginner. plz help.. 

he error i get is.. some java runtime error. I couldn't find a solution.

the example program is in this directory.. file->examples->basics->web->embedded links / loading images

plz help if you could run this program successfully in your computer. share your experience. :)

I want to write a 4 digit number ( say in the range 0000-1024)--- to be entered in the pc keyboard--------  and send it via serial port to an Arduino microcontroller.

I want the arduino to read this number (and set it to an integer variable).. it would be very useful if u can suggest a way for this.

i have found that

 is a function in processing ... which lets us access n send every key pressed in the keyboard individually. but I want a 4 digit number to be entered by the user in the keyboard and send it thro serial port.

 

I'd be happy if suggest a solution for my problem. I am just a novice in the Processing arena.. Hoping to receive any response for this post.. even if its remotely connected.
