This thread contains links to basic technical items judged to be worthy of reference here for building LED projects. This is a good place to start studying if you are just starting to learn about LEDs and how to plan your project.

NOTE: quickar has changed the pwm module they are selling. they are now selling a PIC-based module with a much smaller form factor. they no longer sell 555-timer based pwm modules like the baktronics kit.
