Please Note:
Control and Interfacing circuits includes PC output interfaces, Infra red circuits and even an automatic curtain controller. All circuits are listed alphabetically on the Circuit Index page and in date order on the update page. All contributors are listed on the credits page.

If you have problems try my help page first. Most circuits on this site use SI Notation. Due to large volumes of email, I regret that I can only answer questions about circuits on my site.
