Analog Random Numbers

Using an Arduino and a noise source

It’s easy enough these days to generate random numbers digitally using a computer program. But there is also an analog approach: the project described here processes the noise produced by a transistor junction using an Arduino. The random numbers so generated can be used in various interesting experiments and will even lead us a little into the world of mysticism.

Hello

I do not understand how to start the program
Processing? Should I download a program
into the program Processing?
If so, where can I find this software?
Link Software does not work.

Hi Mr. Kristenson,

You have to download the processing compiler/editor from the webpage
https://processing.org/download/
You can also download without any donation (which they ask for).
Remember that you have to select your operating system before download
After download, start the processing editor and copy the published sourcecode with copy and paste into the editor.
You can save it then with the help of the editor file menu in a folder of your choice.
Then you have to select the right port number in the windows system manager
(with connected arduino).
After starting the software, you can see the user interface shown in the article, and the recording process automatically starts to run.

I hope I could help you with this hint. If you are not so familiar with that subject, maybe you should look first for help in the appropriate literature in books or on webpages. The article you refer to asks for basic knowledge of the arduino and its connection to a PC as well as the use of Processing.

Much success and kind regards: Kurt Diedrich

Hallo Kurt

I'm sorry, but I can not find "published sourcecode"?
But I found the program for Arduino in Elektor Magazine.

Hello Per,

I checked the article in the magazine: You are right: The code is missing. As I am only a freelance writer, I don't know the reason for this decision. But I have an idea how to solve the problem: please go to my German website

www.subroutine.info

then go to the fourth article:
"Arduino-Applikation: Analoger Quantenzufallsgenerator (10.10.2016)"
then click on the link "mehr".
On the page appearing then, please click on " Software" and you will find yourself on the page with the listing.
With copy and paste you can put the code in the editor.
If you still will have problems, you are invited to write me an email to the address on my website. I check the mails coming in there around each second day.
The code seems to be in a mess, but it will be corrected automatically after putting it in the editor again.

Much success and greatings: Kurt
