Simple serial RGB LED controller and driver

Simple serial RGB LED controller and driver

Pete writes –

“If you want to build your own multiple RGB LED display that you can control from either a PC or a dedicated controller then this project will let you do just that.

The project on this page came about when while I was developing a more complex intelligent driver. During that work I put together a simple Red/Green/Blue Pulse Width Modulation LED driver that has a serial interface. The RGB values to control the LED brightness are sent to the PWM driver over this serial interface. “ [via] – Link.

    Wow, you must know a lot about LED and controllers. Is any kind of LED be able to use with controller? What do you think about surface mouth? I have read some articles and am still not sure what I like better between two of them.

    The link on this gives a redirect to a 404 but the information is still on the page if you read real fast or hack it out of it with a meat cleaver.
