Anna,
The "Projects" Link at the top of the page will take you to all of the projects listed on this site. You can also get there with this url: http://www.electronics-lab.com/projects/index.html
If you do not find anything useful in the projects section, please post a request for circuits in the "Circuits/General Requests" forum. It is here: http://www.electronics-lab.com/forum/index.php?board=22.0
Many members read the posts in the circuit request forum and will reply.
I just posted a request for assistance in developing an LED Rainbow Light. I am sorry that I am not sure where it would be posted, so if you have any suggestions, or would like tomove it, I would appreciate the help.
