This section will encompase basic circuits people might use. If a schematic is found to be flawed, it will be repaired or removed.

LEDs, 555s, PWM, Flashers, and Light Chasers

I'm moving this article to blog format to allow me greater flexability in editing. Please, do not comment in the blog, if you do I will delete it. If you want to leave a comment do it here.

One of the most common requests at All About Circuits is various methods of flashing LEDs. I'll try to show most of the techniques used for this purpose that have been covered on this site, explaining how and why along the way.

I'm going to use this space to link to projects I am currently working on, or have shelved with the intention of getting back to them (there are several in that catagory). I tend to jump around a bit, but you notice I'm trying to organize my blogs as a unit, a minibook if you will.

If you wish to respond to a project then do so in the thread where the project is stashed, in the link provided. Thanks.
