The prototype uses 12 LEDs charlieplexed to a PIC 12f683. It uses PWM to fade the light around the disc. Only two LEDs are lit at any one time.

  • Have you played around with slowing this beacon down? I am trying to do this exact project using a PIC 12F683 and Warm White LEDs to be as realistic as possible to a lighthouse.

  • HI Joe, yes it's easy to do you just change a couple of values in the source. Super bright white leds could make quite a nice effect. The source code is available to download on my blog if you're interested. Link is up in the "more info" panel
